• Redundancy Check
• PDM
A high priority means more system resources are allocated to the Rebuild,
Synchronize, Migrate, Redundancy Check and PDM function and less to routine
read/write activity. As a result, the function in progress goes faster but the disk
array takes longer for reads and writes. A low priority has the opposite result.
1. Type 7 and Enter to access Priority.
The CLU takes you through the list of functions one-by-one.
Current rebuilding priority: High
Current synchronization priority: High
Current migration priority:
High
Current redundant check priority: High
Current PDM priority:
High
Change to low RBLD priority for LD 2(y/n)?>y
2. Press Y and Enter to change Rebuilding priority. Press N and Enter to leave
it unchanged.
3. Repeat the same procedure for the other functions.
After the last function, the Screen returns to the Disk Array Properties menu.
Hot Spare Policy
A Hot Spare is a disk drive not assigned to a disk array but available to replace a
failing disk drive that belongs to a disk array. This function enables you to
designate physical drives as hot spares and to specify the hot spare policy.
Hot spare policy is either Global or Dedicated. A Global spare can be used by
any disk array that needs it. A Dedicated spare can only be used by a specific
disk array.
1. Press 8 and Enter to access the Hot Spare Policy.
Current hot spare policy:
Global
Change to Dedicated hot spare policy for LD 1(y/n)?>y
2. Press Y and Enter to change hot spare policy. Press N and Enter to leave it
unchanged.
If you changed the policy to Dedicated, the Physical Drives Selection screen
appears. You must select one drive as the hot spare for this disk array.
