How to upgrade an Enterprise platform to disk mirroring

Disk drive slots

This section tells how to upgrade CentreVuCall Management System (CMS) on a Sun Enterprise 3000 or 3500 computer from a nonmirrored system to a mirrored system.

Before you begin, you must understand the drive slot arrangement in your system.

In an Enterprise 3000 computer, there are 10 slots, allowing up to five disks for each mirror. Each slot is labeled with a number 0 through 3 or 10 through 15; there are no slots numbered 4 through 9. All the drive slots are on controller 0.

In an Enterprise 3500 computer, there are eight disk drive slots, four in each of two bays. The slots in the lower bay are labeled 0 through 3 and are on controller 0; the slots in the upper bay are numbered 4 through 7 and are on controller 1. In a mirrored system, slots 0 through 3 are reserved for the original disks, and slots 4 through 7 are reserved for the mirror disks.

The slot number is the drive’s target number, which becomes part of the device name. A drive in slot 1, for example, has the device name c0t1d0. The drive in slot 0 is always the primary boot disk.

In an Enterprise 3000 mirrored system, mirror disks are normally installed in target number order, beginning with the first empty slot. That makes it difficult to predict the mirror layout on an upgraded system. In an Enterprise 3500 mirrored system, however, mirror disks always go in the upper bay. If you are mirroring a two-disk system, for example, the two original disks would already be installed in slots 0 and 1 in the lower bay, and you would install the two new disks in slots 4 and 5 in the upper bay.
