IMPORTANT NOTE

This procedure is to be used ONLY when the LD(s) are in either "DEGRADED" or "OPTIMAL" state. It should NOT be used when the LD is in a "DEAD" or "Fatal Fail" state. Using this procedure for a dead Logical Drive may result in lost data with little or no chance of recovery.

Final Outcome to be :
o ID4 being ONLINE within the Raid1 LD1

Steps to follow :

- go to "view and edit Drives"
- select ID4 (NONE/USED #1)
- select "add Global spare"
- designate ID4 global spare

- go back to the root of the firmware menu (hit Escape)
- go to "view and edit Configuration parameters"
--> select Disk Array Parameters
--> select Rebuild Priority and set it to "Low", "Normal", "Improved", or "High"

(when selecting "Improved" or "High", discuss with the customer that I/O may be impacted). The value is typically set to normal.

The higher the priority selected, the greater amount of system
resources required. For example, specify low to perform the rebuild
after other firmware processes complete.

- go back to the root of firmware menu (hit Escape)
- go to "view and edit Logical drive"
- select the logical drive that needs to be rebuilt (should be "MISSING DISK")
- choose "rebuild a logical drive"
- watch the "manual rebuild" kick off
- once the rebuild is running go back to root menu

Additional Information
For additional resources see:

Sun StorEdge 3000 Family RAID Firmware 4.2x User's Guide

See Chapter 6 for Drive Status description USED DRV.
The drive was previously configured as part of a logical drive from which it has been removed; it still contains data from this logical drive.

If the "sccli" commands will be used, see the Sun StorEdge 3000 Family CLI 2.5 User Guide

and Technical Instruction 1005062.1 How to use the sccli command to configure and unconfigure Global Spare Disks in Sun Storage 3310, 3320, 3510, and 3511 Arrays.
