Configuration Verification Service Aid
The Configuration Verification service aid enables you to determine the relationship
between SSA logical units (hdisks) and SSA physical disk drives (pdisks). It also
displays the connection information and operational status of the disk drives.
Note: User applications communicate with the hdisks; error data is logged against
the pdisks.
To use the Configuration Verification service aid:
1. Select Configuration Verification from the SSA Service Aids menu to display a list
of pdisks and hdisks (see “Starting the SSA Service Aids” on page 7-31).
