Volume Manager Configuration

Disk Label

On Solaris only: If client data is configured in Volume Manager volumes, be sure to label

all secondary devices using the format command (label option). Labeling the

secondary disks prevents Volume Manager from marking the disks as disabled (if they

are split from their primary disks) during a system reboot.

While a secondary disk is synchronized with its primary, the secondary is invisible to

Volume Manager. When the secondary is split off from its primary disk, the secondary

becomes visible again. If the secondaries are labeled (using the format label

command), Volume Manager will not disable the disks when they are split.

Disk Types

There are important restrictions involving the use of Volume Manager with NetBackup’s

Extended Frozen Image Services.

Note If these restrictions are not observed, the backup will fail.

◆ Do not include secondary (mirror) disks in a Volume Manager disk group.

◆ The Volume Manager disk group must contain disks of one vendor type only. Do not

configure disks of different vendors in the same Volume Manager disk group.

◆ The vendor type of the frozen image method must match the vendor-type of the disks

in the Volume Manager disk group.

Concerning these restrictions, refer to the next two diagrams.
