Diagnostic Information for Multiple Bus Systems manual). The microcode level is shown
in the ROS level field.Alternatively, give the following command:
lscfg -v1 adapter
where adapter is the ID of the adapter that you want to check.
Youcan determine the disk drive microcode level by using the Display/Download Disk
Drive Microcode SSAservice aid (see “Display/Download Disk Drive Microcode Service
Aid”on page 393).
Maintaining the Adapter Microcode
Updates to microcode can be delivered on several types of media, or you can get them
from web page http://www.storage.ibm.com/hardsoft/products/ssa
1. Install the microcode as described in the instructions that are provided with the
installation media.
2. Run the cfgmgr command (if you have not already done so) to download the new
microcode into the SSAadapter.
3. If the SSAloops that are connected to this adapter contain two or more SSA
adapters, and those adapters are installed in two or more using systems, load the
adapter microcode, then run the cfgmgr command on each using system.
If the level of the microcode that is stored in the using system is higher than the level of
the microcode that is installed on the SSAadapter, the higher-level microcode is
automatically downloaded to the adapter when the using system runs its configuration
method.
Maintaining the Disk Drive Microcode
Todownload disk drive microcode, use the Display/Download Disk Drive Microcode
SSAservice aid (see “Display/Download Disk Drive Microcode Service Aid”on
page393).
