Using mkdev to Configure a Physical Disk
To use mkdev to configure an SSA physical disk, specify the following information:
Parent ssar
Class pdisk
Subclass
ssar
Type You can list the types by typing: lsdev -P -c pdisk -s ssar
ConnectionLocation
15-character unique identifier of the disk drive. You can determine the unique
identifier in three ways:
v If the disk drive is already defined, you can use the lsdev command to
determine the unique identity, as follows:
1. Type lsdev -Ccpdisk -r connwhere and press Enter.
2. Select the 15-character unique identifier (UID) for which characters 5
through 12 match the serial number that is on the front of the disk drive.
v Construct the 15-character unique identifier from the 12-character SSA UID
that is shown on the label that is on the side of the disk drive. You can
recognize the UID by its three-character suffix “00D”.
v Run the ssacand command, and specify the adapter to which the physical
disk is connected. For example:
ssacand -a ssa0 -P
Using mkdev to Configure a Logical Disk
To use mkdev to configure an SSA logical disk, specify the following information:
Parent ssar
Class disk
Subclass
ssar
Type hdisk
ConnectionLocation
15-character unique identifier of the logical disk.
If the logical disk is a system disk, you can determine the unique identifier in
three ways:
v If the logical disk is already defined, you can use the lsdev command to
determine the unique identity, as follows:
1. Type lsdev -Ccdisk -r connwhere and press Enter.
2. Select the 15-character unique identifier (UID) for which characters 5
through 12 match the serial number that is on the front of the disk drive.
