First Virtual Communications 3000 user manual Adding a Global Spare, Viewing all Logical Drives

Voyager 3000 User Guide

The status of the SCSI drives are shown by selecting the View and Edit SCSI Drives option from the Main Menu (Figure 4-11). A list of the SCSI drives and their status is shown, as in Figure 4-22.

Figure 4-22 Viewing all Logical Drives

The status table shows the first three drives as part of logical volume 0. These have a status of ON-LINE. In this case the available capacity will be 8190MB because the equivalent capacity of one of the drives is used for parity information.

The capacity of the second logical volume will be 4095MB as the two drives form a mirror set with the equivalent capacity of a single member.

Adding a Global Spare

A global spare will now be created on the last remaining drive (drive 2 of channel 1). A global spare is a spare drive that is accessible to all the logical volumes on the Voyager 3000 system. This means that if a drive fails in either of the two RAID sets created in the examples above the global spare will take over for the failed drive. In this example a Global Spare will be created on drive 2 of channel 1. To assign the Global Spare select the View and edit SCSI drives option and select the drive (drive 2 of channel 1) and press eon it. A dialog like that in Figure 4-23 appears.

Figure 4-23 Adding Global Spare drive

Select the Add Global Spare Drive option and answer YES to the prompt.

To create Local Spare select Add Local Spare Drive and then select the logical volume to which you want to assign the local spare drive. Answer yes to the prompt.

It is also possible to assign a local spare drive when the RAID set is being created. This is done by selecting the Add Spare Drive option as shown in Figure 4-17.
