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 drive.
Notes:
1. User applications communicate with the hdisks; error data is logged against the
pdisks.
2. If a disk drive that has been formatted on a machine of a particular type (for
example, a personal computer) is later installed into a using system that is of a
different type (for example, a large host system), that disk drive is configured only
as a pdisk during the configuration of the using system.
In such an instance, use the Format service aid to reformat the disk drive, then give
the cfgmgr command to correct the condition.
To use the Configuration Verification service aid:
1. Select Configuration Verification from the SSA Service Aids menu (see “Starting
the SSA Service Aids” on page 376). A list of pdisks and hdisks is displayed:
