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
to install the microcode to adapters.
cfgmgr
13.To complete the device driver upgrade, you must now reboot your system.
14.To confirm that the upgrade was a success, type
0,1... for all SSA adapters. Check the ROS Level line to see that each
adapter has the appropriate microcode level (for the correct microcode
level, see the above mentioned web-site).
15.Run
lslpp -l|grep SSA
are above the levels shown in the list on the above mentioned web-site. If
any of the SSA filesets are at a lower level than those shown in the above
link, please repeat the whole upgrade procedure again. If, after repeating
the procedure, the code levels do not match the latest ones, place a call
with your local IBM Service Center.
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
turn.
Note
Allow ssadload to complete on one system before running it on another.
