Configuring Primary and Secondary Disks

108 NetBackup ServerFree Agent System Administrator’s Guide

▼ Configure the arrays, depending on your requirements

The next steps depend on the results of the pairdisplay listings and the requirements

of your site.

◆ If all required disks are correctly paired (status of PAIR), the primary-secondary

configuration is finished.

◆ If required disks are paired but currently split (PSUS, SSUS), or if they are not paired

at all (SMPL), you must resynchronize or configure them, respectively.

Note If a mirror-type frozen image backup attempts to access a disk that is split or not

paired, the backup fails with a status code 11.

◆ If disks are paired but need to be unpaired or otherwise reconfigured, you must split

them and create a new association.

If disks are split:

1. Enter the following to resynchronize the split disks:

pairresync -g groupname -d dev_name

where groupname is the name listed under dev_group, and dev_name is the device

name, as defined in the configuration files. To resynchronize the disks listed as split

(PSUS, SSUS) in the above example (see “Resulting output:” on page 106), enter:

pairresync -g wiltest -d dev2

2. Enter the following to view the result:

pairdisplay -g wiltest -d dev2 -CLI -fc

When the resynchronization starts, the Status column reads COPY. When it is nearly

completed, the Status column reads PAIR (see the % column for percentage

completion).

If disks are not paired:

1. Enter the following to create a pair of primary and secondary:

paircreate -g groupname -d dev_name -vl

where groupname is the name listed under dev_group, dev_name is the device

name, as defined in the configuration files, and -vl specifies that the current instance

number is the primary.

To associate the dev3 disks as a pair (the ones listed as SMPL in the above example;

see “Resulting output:” on page 106), enter the following:

1 2 ... 117 118 119 120 121 122 123 124 125 126 127 ... 181 182
