Administering disks

Installing and formatting disks

3If you want to use enclosure-based naming, use vxdiskadm to add a non-persistent simple disk to the bootdg disk group, change back to the enclosure-based naming scheme, and then run the following command:

#/etc/vx/bin/vxdarestore

Note: If not all the disks in bootdg go into the error state, you need only run vxdarestore to restore the disks that are in the error state and the objects that they contain.

Persistent simple or nopriv disks in non-boot disk groups

If an imported disk group, other than bootdg, consists only of persistent simple and/or nopriv disks, it is put in the “online dgdisabled” state after the change to the enclosure-based naming scheme.

To remove the error state for persistent simple or nopriv disks in non-boot disk groups

1Deport the disk group using the following command:

#vxdg deport diskgroup

2Use the vxdarestore command to restore the failed disks, and to recover the objects on those disks:

#/etc/vx/bin/vxdarestore

3Re-import the disk group using the following command:

#vxdg import diskgroup

Installing and formatting disks

Depending on the hardware capabilities of your disks and of your system, you may either need to shut down and power off your system before installing the disks, or you may be able to hot-insert the disks into the live system. Many operating systems can detect the presence of the new disks on being rebooted. If the disks are inserted while the system is live, you may need to enter an operating system-specific command to notify the system.

If the disks require low or intermediate-level formatting before use, use the operating system-specific formatting command to do this.

Note: SCSI disks are usually preformatted. Reformatting is needed only if the existing formatting has become damaged.

The following sections provide detailed examples of how to use the vxdiskadm utility to place disks under VxVM control in various ways and circumstances.
