Prerequisites

If possible, do a CMSADM backup before you add or replace a disk drive. See your CMS software installation, maintenance, and troubleshooting document for this procedure.

Before you attempt to replace defective data (nonboot) disks, try to print the current setup for all ACDs. This information must be readministered after you install replacement disks.

Disk drive compatibility with CMS loads

When a new or replacement disk drive is installed in an older system, the CMS load may not be compatible with the disk drive if the CMS configuration files have not been updated. Two configuration files (/olds/disk.conf and /olds/olds-funcs) must be edited or replaced with the correct information. Contact the Avaya technical support organization for assistance.

Disk drive configurations

The computer supports a four-disk mirrored configuration. On only the V880, the configuration can be expanded to six disks with a field upgrade. The Sun Fire V880 supports 73-GB disks and the Sun Fire V890 supports 146-GB disks.

! Important:

Disks cannot be swapped between the V880 and V890 models.
