Create a Array in MSA 1510i
Background parity initialization is currently
queued or in progress on Logical Drive 5 (1907672 MB, RAID 5). If background parity initialization is queued, it will start when I/O is performed on the drive. When background parity initialization completes, the performance of the logical drive will improve.
Is it running or queued? Anyway to check it?
Thank

Re: Create a Array in MSA 1510i
Here are the steps:-
1. Connect the MSA serial cable to a controller. The MSA serial cable is delivered with every MSA1000/1500/1510i system.
The cable can also be ordered on spare part number 316131-001.
NOTE: Can NOT use a normal RJ-45 cable as the MSA cable is keyed.
2. Enter the default communication settings for the MSA controller:
19200 baud, 8 data, NO parity, 1 Stop & no Flow Control. These settings are also printed on the 9-pin D-SUB connector
3. Identify which controller that is running in active role by executing 'show this_controller' in CLI on both controllers.
The 'Current Role' field will tell if controller is in Active or Standby role.
4. When Active controller has been identified make sure serial cable is attached to the this controller
5. Run the command
show units
It will show all the LUNS and the Status. In the following formats
CLI> show unit 1
Unit 1:
In PDLA mode, Unit 1 IS LUN 2; In VSA mode, Unit 1 is LUN 1
Unit Identifier:
Device Indentifier: 600805F3-00006B20-AE277D4B-B0D100F7
Preferred Path: Controller 1 (this controller)
Cache Status: Enabled
Max Boot Partition: Disabled
Volume Status: VOLUME OK
Parity Init Status: 3% complete
5 Data Disk(s) used by lun 1:
Disk107: Box 1, Bay 07, (B: T: L: 2;04:07)
Disk108: Box 1, Bay 08, (B: T: L: 2;04:08)
Disk207: Box 2, Bay 07, (B: T: L: 2;04:07)
Disk208: Box 2, Bay 08, (B: T: L: 2;04:08)
Spare Disk(s) used by lun 1:
No spare drive is designated
Logical Volume Raid Level: DISTRIBUTED PARITY FAULT TOLERANCE
(RAID5)
stripe_size=16KB
Logical Volume Capacity: 173,658MB
This will show you the percentage of the Parity Initialization.
Hope it helps.
Regards,
Sunny

Re: Create a Array in MSA 1510i
Volume Status : VOLUME OK
Mirror Init Status: waiting for first write
It is sufficient to write a signature or simple partition to get the process running.

"Parity Init Status: waiting for first write"
The Parity Intialization is probably not kick off. :(
