2. For status information on a particular pair of disks, enter the following:

pairdisplay -g groupname -d dev_name [-CLI] [-fc]

where dev_name is the name specified in the configuration files under dev_name.

Note If no primary-secondary associations (pairings) exist, all disks are listed as SMPL in

the P/S column. To create a primary-secondary pairing, see “If disks are not

paired:” on page 108.

The following describes important headers in the pairdisplay listing.

Group

This is the dev_group name defined in the configuration file.

PairVol

Lists the devices by device name. In the above output, dev1 is listed twice: the first line is

the primary disk, the second is the mirror (secondary). This is shown under the P/S

column: P-VOL indicates the primary, S-VOL the secondary.

L/R

Indicates local or remote host, with respect to the current instance number.

Port#

The port number for the disk, configured by means of the array’s dedicated console (not

from a NetBackup host).

TID

The SCSI or fibre channel target ID number of the disk, configured by means of the array’s

dedicated console (not from a NetBackup host).
