							CHAPTER 8. SYSTEM BACKUP FOR DEFINITY G3r
4.
5.
6.If the user requests that the backup take place on the standby processor, the standby
processor must be in service, shadowing enabled, and refresh completed (E16). If the
file system of the tape is a core-dump file system, the command will be denied (E17).
For incremental backup, if the file system type of the tape is an installation file system,
and the vintage of the boot image running in the active processor matches the vintage of
the boot image on the tape, then the system will first configure the tape with the same
configuration as is currently running. If the in-memory vintage does not match the vintage
on the tape, the 
backup command will be denied (E18). The tape must be manually
configured in this situation.
If the 
incremental option is specified and the file systems of the disk and tape are not
the same, the command will be denied (E23).
For full backup, if the tape has installation, large, or core-dump file system, backup will
proceed.
If errors are encountered in the operations described above, the backup operation should
not be attempted.
Restore Command
The restore command allows the user to copy files from a tape (which was used to backup the
disk) to the disk. This operation will be used for system installation, system upgrades/updates, or
after a repair of the disk has occurred.
Command Syntax
restore disk [active | standby | SPE_A | SPE_B | both | either] [incremental | full]
The options, [active | standby | SPE_A | SPE_B | either I both ], specify which mass storage
system the user wishes to restore.
Invoking the 
restore command with the SPE_A option causes files from the tape associated with
processor 
A to be copied to the disk on that same processor. SPE_A is the default in a simplex
system.
Invoking the restore command with the 
SPE_B option causes files from the tape associated with
processor 
B to be copied to the disk on that same processor.
Invoking the 
restore command with the active option causes the files on the tape on the active
procesor to be copied to the disk on the same processor.
8-15 
						

							CHAPTER 8. SYSTEM BACKUP FOR DEFINITY G3r
Invoking the restore command with the standby option causes files from the tape associated
with the standby processor to be copied to the disk on that same processor.
Invoking the 
restore command with the both option forces the system to copy files from the
tape-to-disk device on both mass storage systems concurrently. If the standby processor is inac-
cessible, the command will fail on both processors. This means that no data will be written on
either of the specific processors. The default in a duplex system is both.
Invoking the restore command with the either option forces the system to copy files from tape to
disk device in both mass storage systems concurrently. If the standby processor is inaccessible,
the command will still execute on the active processor and files will be copied to the disk.
Invoking the command with the 
incremental option causes a selective restore operation to be
performed. in this case, all files on the tape that are marked as “good” and which have a newer
last file update time than the corresponding disk files, are copied to the disk. Not copying files
marked as “bad” ensures that corrupted files do not overwrite good (but possibly older) files. The
default value is 
full.
If a full disk restore is specific, the entire contents of the tape are copied to the disk. All files,
“good” and “bad,” regardless of the last file update times, are copied to the disk.
Command Operation
For an incremental restore, the files are copied in the following manner. Before each file is
copied from the tape to the disk, the file on the disk is marked as “bad.” When the file from the
tape has been completely copied over onto the disk the file is then marked as “good” on the
disk. This process ensures that if the system were to reboot in the middle of the operation, files
in the process of being copied will not be usable because they are still marked as “bad.”
For a 
full restore operation, the files are copied in the following manner. When the process
begins, all files on the disk will be marked as “bad.” When the entire tape has been copied to
disk the files on the disk will be marked as “good.” The only exception to this is that a file which
is marked as “bad” on the tape will retain this marking on the disk also.
The success or failure of the command for each processor will be displayed on the screen, as
shown below.

							CHAPTER 8. SYSTEM BACKUP FOR DEFINITY G3r
The following operational rules apply to the restore command:
1.
2.
3.
4.
5.
6.The 
restore command will only be allowed to run if there are no other applications
currently using the MSS devices (E3).
The options entered by the user will be validated against the system configuration, and
the target devices for the restore command are determined (E11).
The disk must be in service (E13). The tape must be in service (E14).
If the user requests that the restore take place on the standby processor, the standby
processor must be in service, shadowing enabled, and refresh completed (E16).
If the file system of the tape is a core-dump file system, the command will be denied
(E17).
If the file system of the tape is an installation file system, the command will be denied
(E22). If the 
incremental option is specified and the file systems of the disk and tape
are not the same, the command will be denied (E23).
If errors are encountered in the operations described above, the restore operation should
not be attempted.
Error Conditions
The following is a list of all error messages displayed to the user. If any of these error conditions
can be attributed to hardware failures or disk/tape configuration problems, they will be logged
with the maintenance subsystem. Error messages that are caused by a user entering improper
command options are not logged with the maintenance subsystem; the user is notified of the
error.
For each error message listed, an identifier is provided which indicates where on the screen the
message will occur.
A failure can occur on either processor in a duplicated system. When the error is displayed, it is
associated with the processor on which the error was encountered.
E1login:cha station 51001 has data locked
This error message is displayed for the save translation command when there is an
active translation update command.
E2 (M)TTI activation or deactivation is in progress; this command is not
allowed at this time
When TTI activation or deactivation is in progress, save translation cannot occur.
The TTI activation or deactivation must be suspended first.
E3 (M)loginid: command has cmd conflict
This message means that the user logged in with ‘Ioginid’ has a command that con-
flicts with the MSS command you are using.
E4 (W)No tape in tape drive
This message means that the tape cartridge is missing from the drive.
