HP Veritas Volume Manager 5.0 -UX 11i v3 Enclosure-based naming, # vxdisk path egrep diskname

Administering disks

Disk devices

79

The syntax of a legacy device name is c#t#d#, where c# represents a controller on a host bus adapter, t# is the target controller ID, and d# identifies a disk on the target controller.

Fabric mode disk devices are named as follows:

■Disks in supported disk arrays are named using the enclosure name_# format. For example, disks in the supported disk array name FirstFloor are named FirstFloor_0, FirstFloor_1, FirstFloor_2 and so on. (You can use the vxdmpadm command to administer enclosure names.)

■Disks in the DISKS category (JBOD disks) are named using the Disk_# format.

■Disks in the OTHER_DISKS category (disks that are not multipathed by DMP) are named using the fabric_# format.

Enclosure-based naming

Enclosure-based naming operates as follows:

■All fabric or non-fabric disks in supported disk arrays are named using the enclosure_name_# format. For example, disks in the supported disk array, enggdept are named enggdept_0, enggdept_1, enggdept_2 and so on. (You can use the vxdmpadm command to administer enclosure names. See “Administering DMP using vxdmpadm” on page 139 and the vxdmpadm(1M) manual page for more information.)

■Disks in the DISKS category (JBOD disks) are named using the Disk_# format.

■Disks in the OTHER_DISKS category (disks that are not multipathed by DMP) are named as follows:

■Non-fabric disks are named using the c#t#d# or disk## format.

■Fabric disks are named using the fabric_# format.

See “Changing the disk-naming scheme” on page 91 for details of how to switch between the operating system and enclosure based naming schemes.

To display the native OS device names of a VM disk (such as mydg01), use the following command:

#vxdisk path egrep diskname

For information on how to rename an enclosure, see “Renaming an enclosure” on page 155.
