10. Click Next again to install the driver. 11. Click Finish . 12. Close the Device Properties dialog box. The autoloader now appears in Device Manager under Medium Changers as a Dell (tm) PowerVault (tm) 124T Autoloader , and is ready to use. Enabling LUN Support in Linux To verify the detection of a tape drive, administrators should check for its entry in /proc/scsi/scsi. Current versions of Linux may not scan the logical storage unit (LUN) ID of every device. This can result in some PowerVault devices not being identified or listed in the /proc/scsi/scsi output. Administrators can follow these steps to enable support for such devices. 1. Type cat/proc/scsi/scsi . The output will look similar to the following: Attached devices: Host: scsi3 Channel: 00 Id: 00 Lun: 00 Vendor: IBM Model: ULTRIUM - TD3 Rev: 5BG2 Type: Sequential - Access ANSI SCSI revision: 03 2. Identify the host adapter, channel number, target ID number, and LUN number for the first LUN of the device to be configured. In this example, the Certance Ultrium 2 (a drive in the PowerVault 124T) is shown at the address, or nexus, 3 0 0 0 — which means host adapter 3, channel number 0, ID 0, and LUN 0. The PowerVault 124T always has the tape drive at LUN 0 and the robot at LUN 1. 3. For each LUN that needs to be discovered by Linux, issue the following command: echo scsi - add - single - device H C I L >/proc/scsi/scsi H C I L refers to the nexus described in step 2 . So, with the PowerVault 124T robot configured at LUN 1, type: echo scsi - add - single - device 3 0 0 1>/proc/scsi/scsi The echo command will force a scan of each device at the given nexus. 4. Type cat /proc/scsi/scsi again to verify that all devices are now listed. The output will look similar to the following: Attached devices: Host: scsi3 Channel: 00 Id: 00 Lun: 00 Vendor: IBM Model: ULTRIUM - TD3 Rev: 5BG2 Type: Sequential - Access ANSI SCSI revision: 03 Attached devices: Host: scsi3 Channel: 00 Id: 00 Lun: 01 Vendor: DELL Model: PV - 124T Rev: V31 Type: Sequential - Access ANSI SCSI revision: 03 Administrators should add the echo command to the Linux boot scripts because the device information is not persistent and must be created each time the system boots up. One example file that can be used for storing the commands is /etc/rc.local. Note that configuring additional devices on a server or a storage area network (SAN) can cause the devices to be reordered, which requires administrators to modify the commands. If the Fibre Channel adapter supports Persistent Bindings or an equivalent function, it can be enabled to reduce the chance of devices being reordered upon discovery. The other way to enable LUN support is to recompile the kernel and enable LUN scanning in the Adaptec driver, but it requires advanced knowledge of Linux and will not be covered here. However, it will allow the server to always boot and see the device without any manual procedures. Enabling LUN Support in Netware 1. From the System Console, verify the LUN device is not being detected by using the list storage adapters command. Typical output where only the tape drive is being recognized: 0x08 [V321 - A3] Adaptec SCSI Card 39160/3960D - Ultra160 SCSI [slot 201] 0x15 [V321 - A3 - D5:0] IBM ULTRIUM - TD3 5BG2 0x09 [V321 - A4] Adaptec SCSI Card 39160/3960D - Ultra160 SCSI [slot 202] 2. From the System Console, type nwconfig . 3. Select NCF files Options from the Configuration Options screen. 4. Select Edit STARTUP.NCF from the Available NCF Files Options screen. 5. Add the /LUNS switch to the load line of the appropriate SCSI driver. If a dual channel card is installed and the user is unsure which channel the LUN device is attached to, simply edit both lines. NOTE: This procedure must be run each time the server is booted. Also, if backup application services are running (for example, they automatically start when the OS loads), they must be disabled and re - enabled after the above procedure.
LOAD ADPT160M.HAM SLOT=201 /LUNS LOAD ADPT160M.HAM SLOT=202 /LUNS 6. After the STARTUP.NCF file has been edited, save the file and reboot the server to activate the new STARTUP.NCF. 7. Upon reboot navigate to the System Console and type scan all . This will start a scan of all the LUNS on each adapter. 8. When the scan is complete, verify the LUN device has been detected using the list storage adapters command. Typical output with both the tape drive and loader being recognized: 0x08 [V321 - A3] Adaptec SCSI Card 39160/3960D - Ultra160 SCSI [slot 201] 0x16 [V321 - A3 - D5:1] DELL PV - 124T 0031 0x15 [V321 - A3 - D5:0] IBM ULTRIUM - TD3 5BG2 0x09 [V321 - A4] Adaptec SCSI Card 39160/3960D - Ultra160 SCSI [slot 202] Netware may display unbound device , meaning a driver is not bound to the loader unless a driver from a backup software is loaded. This does not prevent the backup application from detecting the LUN and binding the appropriate driver. Back to Contents Page NOTE: The user must type the command scan all upon OS boot every time. If backup software services automatically start on OS boot, the user must disable them, run the scan all command, and re - enable the services. NOTE: Netware may display unbound device meaning a driver is not bound to the loader unless a driver from a backup software is loaded. This does not prevent the backup application from detecting the LUN and binding the appropriate driver.
Back to Contents Page - 3 Autoloader Users Guide Overview Data backup is essential to protect irreplaceable information. Backing up data to magnetic tape is an easy, cost - efficient method used by many small and medium businesses. However, most enterprises have so much data that a single backup tape is not enough; the information has to be spread across numerous tapes. To avoid constantly changing tapes manually, many tape backup solutions include a PowerVault 124T LTO - 3 autoloader. Each autoloader is a device that includes a robot, a tape drive and one or two magazines for tape cartridges. The users application can automatically load and unload tape cartridges as required for data backup or data retrieval. Dell PowerVault 124T LTO - 3 autoloaders provide a compact, high capacity, but low cost method for easy, unattended data backup. The PowerVault 124T LTO - 3 contains an IBM LTO - 3 tape drive, and one or two magazines that can hold up to eight cartridges each. The user can insert a single cartridge directly through a media door (mailslot) that can be password protected. From the media door (mailslot), the user can insert the cartridge into the tape drive provided there is no cartridge already in the drive, or into a magazine slot provided there is no cartridge already in the slot. The front panel on the autoloader includes a liquid crystal display (LCD) screen and four function keys. A scrolling menu on the LCD screen allows the user to obtain information from the autoloader and enter commands. The front panel also includes two light emitting diodes (LEDs) indicating the autoloaders ready status and error status. The PowerVault 124T LTO - 3 connects to the users host server through a Small Computer System Interface (SCSI) connection allowing the host to send data and commands automatically. The unit also can connect to an Ethernet which allows the user to perform administrative functions and download system updates. The autoloader is SCSI - 3 compatible and operates as a single SCSI ID/two LUN data storage device and provides a compressed capacity of 1.24 Terabytes and a sustained data transfer rate of 245 GB per hour (native) or as high as 490 GB per hour compressed (assuming 2:1 compression) The autoloader is compatible with the most popular operating systems and environments supporting an Ultra 160 SCSI or an Ultra 320 SCSI LVD interface but requires direct support from the operating system or a compatible backup application to take full advantage of its many features.

Using Cartridges Typically, when you first install the autoloader, you load your cartridges into the magazines and then load the magazines into the autoloader. However, you can insert and eject cartridges individually using the media door (mailslot), or you can eject a magazine, manually load and unload cartridges, then load the magazine back into the autoloader. The autoloader automatically detects the presence of a cartridge in the magazine slot. If you try to perform an illegal operation, the autoloader refuses to perform the operation. For example, if you try to load a cartridge through the media door (mailslot) to the drive but the drive already contains a cartridge, the media door (mailslot) does not unlock and will display an error message. If you try to unload a cartridge from the drive while the autoloader is writing to the tape, the command will not be initiated until the write command is completed. Insert a Single Cartridge When you want to load a single cartridge into the autoloader, you can use the media door (mailslot). However, if the Security option is turned on, you have to enter a valid password to unlock the media door (mailslot) before you can load a cartridge. When you insert a cartridge through the media door (mailslot), you can load it into the tape drive or store it in a magazine. To insert a cartridge in the tape drive: 1.

Using Magazines and Magazine Blanks Inward Side of a Magazine Outward Side of a Magazine NOTE: This function is only allowed if the bar code reader is enabled.
The autoloader will not run unless both magazine bays are properly occupied with either a magazine or a magazine blank. One way that you can close the openings is to use two magazines. If you use only one magazine, then you must fill the other magazine opening with a magazine blank for the unit to become operational. Ejecting a Magazine When you want to remove several cartridges at once, eject the magazine(s) first. To eject a magazine: 1. From the main menu, scroll to Commands , and then press Enter . 2. From the Commands submenu, scroll to Eject , and then press Enter . 3. On the Eject submenu, scroll to Right Magazine or Left Magazine , and then press Enter . You will hear a distinctive popping sound as the appropriate magazine is ejected from the autoloader. Left magazine has been ejected or Right magazine has been ejected appears on the LCD. 4. Grasp the magazine by the handle with one hand and slide it out, supporting it underneath with the other hand. When issuing a Load/Unload command from software, the system automatically ejects the right magazine. To remove the left magazine using the Load/Unload command, you must: 1. Remove the right magazine. 2. Replace the right magazine with a magazine blank. 3. Issue the Load/Unload command again. The system will then eject the left magazine. 4. If you want to have a magazine in the right bay, replace the magazine blank in the right bay with a cartridge magazine. Installing a Magazine To install a magazine into the autoloader, use the following procedure. 1. Grasp the magazine by the handle with one hand and support it underneath with the other hand. 2. Slide the magazine into the magazine bay until it clicks. Make sure that you position the magazine correctly. It should slide into the magazine bay smoothly. If you meet resistance, verify the orientation of the magazine. The magazine is correctly installed when you feel it click into place and the front of the magazine is flush with the front panel. Left Mag Inserted or Right Mag Inserted appears on the LCD. The autoloader automatically proceeds to run an inventory. Manually Operating the Magazine NOTE: Magazines are not interchangeable between drive types. Order the appropriate part numbers when replacing these items. NOTICE: To prevent damage to the autoloader or the magazine, use both hands when removing the magazine from the autoloader, supporting the entire length of the magazine. NOTE: Once you eject a magazine, you must fully remove it or fully reinstall it before powering off the autoloader. Before returning a magazine to the autoloader, manually turn one of the white thumb wheels located on each end of the magazine. If they move freely, the cartridges are properly seated. If the wheels do not turn freely, check the cartridges and remove and replace as needed. NOTICE: Be careful not to turn the knob on the side of the magazine while the magazine is partially inserted into the autoloader. Doing so may cause damage to the magazine or the autoloader.
There are two white thumbwheels, located on each end of the magazine. You can move the slots within the magazine by turning these two white thumbwheels and aligning a slot with one of the two openings. Do not rotate the magazine by inserting your hand and pushing the cartridge carriers. You can use the openings in the magazine to load and unload cartridges from the eight slots within each magazine. To load cartridges into a fully ejected magazine: 1. To load cartridges into the magazine, center a slot within one of the openings located on the side of the magazine. 2. Properly orient the cartridge; tape upright and bar code label facing outward. 3. Fully insert the cartridge into the slot. When pushing the cartridge into the slot, you will feel a small resistance (detent) until the cartridge is properly latched into the slot. All forward progress stops when the cartridge is fully inserted. You can remove a cartridge in the same manner as you insert it. Use the white thumbwheels to center the desired slot(s) in the openings on the side of the magazine. Do not rotate the magazine by inserting your hand and pushing the cartridge carriers. Using your thumb and index finger, pull out the cartridge. You will feel a small resistance, but continue to pull the cartridge until it comes free. To identify a slot: Each slot has an identification number that is exposed when the slots are in the upper section of the magazine. With the magazine removed from the autoloader, you can see the identification mark on the top side of the magazine through one of two windows on the upper surface of the magazine. Each magazine carrier is labeled 1/9, 2/10, 3/11, and so fourth. Lower numbers 1 - 8 reference slots in the left magazine. Higher numbers 9 - 16 reference slots on the right magazine if the optional right magazine is installed. Running an Inventory The autoloader automatically runs an inventory whenever you power it back on or insert a magazine. An inventory checks each magazine slot, the drive, the picker, and the media door (mailslot) to determine if a cartridge is present. If so, it also reads the bar code label, if available. If you need to run an inventory in addition to this, you can do so manually. To perform an inventory manually: 1. From the main menu, scroll to Commands , and then press Enter . 2. From the Commands submenu, scroll to Inventory , and then press Enter . The autoloader scans the bar codes of all the cartridges present.
