Note
You must ensure that:
•You do not attempt to perform this adapter microcode download concurrently on systems that are in the same SSA loop. This may cause a portion of the loop to be isolated and could prevent access to these disks from elsewhere in the loop.
•You do not run advanced diagnostics while downloads are in progress. Advanced diagnostics causes the SSA adapter to be reset temporarily, thereby introducing a break in the loop, portions of the loop may become temporarily isolated and inaccessible.
•You have complete SSA loops. Check this by using diagnostics in System Verification mode. If you have incomplete loops (such as strings) action must be taken to resolve this before you can continue.
•All of your loops are valid, in this case with one or two adapters in each loop. This is also done by using Diagnostics in System Verification mode.
12.Run cfgmgr to install the microcode to adapters.
13.To complete the device driver upgrade, you must now reboot your system.
14.To confirm that the upgrade was a success, type lscfg
15.Run lslpp
16.If the adapters are in SSA loops which contain other adapters in other systems, please repeat this procedure on all systems as soon as possible.
17.In order to install the disk microcode, run ssadload
Note
Allow ssadload to complete on one system before running it on another.
