Upgrading software 
Upgrading software includes upgrading the Boot ROM and system software. Each time the switch is 
powered on, it runs the Boot ROM image to initialize hardware and display hardware information, and

Upgrade method Upgrade object Description 
In-Service Software 
Upgrade (ISSU) System software ISSU enables software upgrade and ensures continues 
packet forwarding. For more information, see Performing 
ISSU. 
The ISSU feature is available only on the HP 5500-EI 
switch.
 
 
Upgrading software through a system reboot 
Upgrading software by rebooting the switch interrupts the ongoing services. If any other method is 
possible, do not use this method.

 IMPORTANT: 
You can assign different names to the image files for different member switches, but must make sure the
 
image versions are the same.   
3.
 Use the  boot-loader file file -url  slot  { all  | slot-number  } {  main | backup } command in user view 
to specify the system software image to be used  at the next startup for each member switch. 
4. Reboot all member switches.

Common patches always include the functions of the previous temporary patches. The patch type 
only affects the patch loading proc ess. The system deletes all of the temporary patches before it 
loads the common patch. 
•   Patch package file 
A patch package file typically contains multiple pat ch files. A patch package file enables you to fix 
bugs for multiple components  by executing a single command. 
Using patch files is more troublesome. Patch file names are strictly  defined and cannot be...

IDLE state 
Patches in IDLE state are not loaded. You cannot install or run the patches, as shown in Figure 44. In this  
example, the memory patch area can load up to eight patches.  
Figure 44  Patches are not loaded to the memory patch area 
 
 
The memory patch area supports up to 200 patches. 
DEACTIVE state 
Patches in DEACTIVE state have been loaded to the memory patch area but have not yet run in the system. 
Suppose that there are seven patches in the patch file  to be loaded. After the...

RUNNING state 
After you confirm the ACTIVE patches are running,  the state of the patches changes to RUNNING and 
the patches are in RUNNING state after system reboot . If you confirm the first three patches are running, 
for the five patches in  Figure 46, the
 ir states change from ACTIVE  to RUNNING. The patch states of the 
system are shown in Figure 47 . 
T

he patches that are in RUNNING state are still in RUNNING state after system reboot.

Installation prerequisites 
Patches are released per switch model. To ensure a successful hotfix operation and normal switch 
operation after the hotfix operation: 
•  Make sure each patch file you  are installing matches the switch  model  and software version. 
•   The loading and installation are performed on all  member switches of an IRF fabric. Before these 
operations, save the same patch files to the storag e media’s root directory of each member switch. 
•    Name a patch file properly....

To uninstall all patches in one operation, use the undo patch install command, which is the same as 
performing  Uninstalling a patch step-by-step .

process.

To load a patch file:   
Step Command 
1.  Enter system view.

2.  Load the patch file on from the storage media (the 
Flash) to the specified memory patch area.  patch load slot

Activating patches 
After you activate a patch, the patch takes effect and is in the test-run stage. After the switch is reset or 
rebooted, the patch becomes invalid.

Deleting patches 
Deleting patches only removes the patches from the  memory patch area, and does not delete them from 
the storage media. The patches turn to IDLE state after this operation. Af ter a patch is deleted, the system 
runs the way it did before it was installed with the patch. 
In an IRF fabric, HP recommends that  you uninstall all patches by using the...
