Performing ISSU 
This chapter describes how to use the In-Service Software Upgrade (ISSU) feature to upgrade software. 
The ISSU feature is available only on the HP 5500-EI switch. 
ISSU overview 
ISSU enables software upgrade and ensures continuous packet forwarding. 
As shown in Figure 50, t
 o ensure high availability for user networks, cross-device link aggregation is 
configured on the IRF member switches at the distribution layer so that every three physical links with the 
same color between...

 IMPORTANT: 
•
  Do not modify the current configuration, plug or un plug cables connected to IRF ports, or delete or 
modify the system software image during ISSU. Otherwise, the upgrade might fail.

State Remarks
 
Init (Initial state)  No ISSU starts or an ISSU upgrade has completed. 
Load  A subordinate switch is being upgraded or 
has been upgraded. To stop the loading 
process, perform a manual or automatic roll  back to revert system software to its 
original version. 
Switchover  The master is being rebooted to trigger a new master election. 
Accept  The ISSU has been accepted. To stop the 
loading process, you have to perform a 
manual roll back to...

Performing an ISSU for a compatible version  
Required. 
Use either approach. 
Performing an ISSU  for an incompatible version  
If you do not execute the issu run switchover  command 
before the rollback timer expires, the ISSU upgrade ends 
automatically, the software reverts to the previous version,...

 116 
Displaying version compatibility 
Before performing an ISSU upgrade, check the version compatibility between the new and current system 
software images, to determine whether ISSU can be  performed, and which ISSU method is adopted. 
After downloading and saving the new system soft ware image, select an ISSU upgrade method 
according to one of the following version compatibility check results: 
•   Compatible —The running system software image is compatible with the new system software 
image. You...

slot-number   With this command executed: 
•
 The master reboots with the current system software 
image, and becomes a subordinate switch after 
reboot. 
• The subordinate switches of the IRF fabric perform 
master election. The winner (the subordinate switch 
specified with the issu load  command) becomes the 
new master. 
The slot-number provided in this command must be the 
same as that specified in the...

 IMPORTANT: 
To upgrade system software of the IRF fabric thro
ugh ISSU when the new and current system software 
image versions are incompatible, make sure that th e multi-active detection (MAD) function has been 
configured for the IRF fabr ic. Otherwise, duplicate IRF fabrics wi ll coexist after the new master (the 
subordinate switch specified with the  issu load command) is rebooted, causing network faults.
