Description
The ssadload command performs microcode downloads to SSA physical disk drives.
The command has three modes of operation:
v Load a specific level of microcode into a specific SSA physical disk drive.
Using the command in this mode, you can force load any available level of
microcode into any compatible SSA disk drive.
v Ensure that either a specific SSA physical disk drive, or all the physical disk
drives that are connected to the system, are using the latest levels of
microcode that are available on the system.
Using the command in this mode, you can ensure that the latest available level of
microcode has been loaded onto all compatible SSA disk drives in the system.
v Show the existing microcode level that is installed on either a specific SSA
physical disk drive, or on all the SSA physical disk drives that are connected
to the system.
Using the command in this mode, you can check the level of microcode on the SSA
disk drives that are connected to the system.
Notes:
1. The microcode files that this command can download have names of the pattern

doing so, however, you might cause a temporary delay in the operating system or in the
user's application program. Do not download microcode to a disk drive that is in
use, unless you have the user's permission. Always refer to the download
instructions that are supplied with the microcode, and check for any special
restrictions that might be applicable. If you are not sure, do not download to disk
drives that are in use.

ssadisk.ros.XXXX, where XXXX identifies the microcode level (also known as the
ROS id) that the file contains. Such microcode files are different from those with
names of the pattern ssadisk.XXXXXXX.YY. These files contain a different type of
disk microcode, and are automatically downloaded by the system configuration
software as necessary. They cannot work with the ssadload command.
disk drives. You need not vary off any volume groups that contain the disk drives. If
the microcode is downloaded to a disk drive that the system is using, the system
might be delayed slightly while the microcode is downloading.
Usually, you can download the microcode to disk drives that are in use. By
