2.3.1 Adding or Moving Disk Trays to Existing Arrays
RAID Manager 6.22 has dynamic capacity expansion capability. If your RAID system
has not used all five drive side channels, you can add disk trays to it and expand the
capacity of the existing drive groups. The existing LUN capacity does not increase.
See “Configuring RAID Modules” in the Sun StorEdge RAID Manager 6.22 User’s
Guide. When expanding to a different configuration, ensure that it is a supported
configuration as documented in the Sun StorEdge A3500/A3500FC Hardware
Configuration Guide.
Note – Disk drives should not be interchanged between A1000, A3500, and
A3500FC. The controller may update its NVSRAM from the (inconsistent) DacStore
in the foreign disks causing an A3x00/A3500FC controller to start behaving like an
A1000 or RSM 2000 controller. If this should occur you will need to reload the
correct NVSRAM into each controller.
The A3000 back-end SCSI transfer rate is set to 20-MB/sec and the A3500 back-end
SCSI transfer rate is set to 40-MB/sec. Interchanging of these controllers can cause
data corruption problems.
You need to power cycle the controller module for the new disk tray to be
recognized in. Be sure the drives contained in the new disk tray are not larger in
capacity than the Global Hot Spare (GHS) drives. This is because the GHS will not
spare a drive that has a higher capacity than itself. To connect the power and SCSI
cables to the new disk tray, and to set the disk tray ID (and the option switch on
D1000 trays), refer to the Sun StorEdge A3500/A3500FC Hardware Configuration Guide.
2.3.2 Adding or Moving Disk Drives to Existing Arrays
You can add new drives to empty slots in your existing array. To add new disk
drives:
1. Insert a disk drive into the tray.
2. Allow time for the drive to spin up (approximately 30 seconds).
3. Run a health check to insure that the drive is not defective.
4. Fail the drive then revive the drive to update DacStore on the drive.
5. Repeat steps 1 through 4 until all drives have been added.
6. New drives are now ready for LUN creation.
