"Parity Initialization Status: In Progress" for long time
Hello,
Two weeks ago I installed 6 new hard disks (HP 500GB 6G 7.2K SFF 2.5-inch 2-ports SAS DualPort Midline, 507610-B21)
in a "HP DL 380 G5" with a "Smart Array P400" (RAM Firmware Revision 2.08, ROM Firmware Revision 2.08).
I created a new logical disk with 5 physical disk in RAID 5 and a spare drive (array B):
[...]
=> ctrl all show config
Smart Array P400 in Slot 1 (sn: P61620D9SUKHBP)
array A (SAS, Unused Space: 0 MB)
logicaldrive 1 (136.7 GB, RAID 1, OK)
physicaldrive 2I:1:1 (port 2I:box 1:bay 1, SAS, 146 GB, OK)
physicaldrive 2I:1:2 (port 2I:box 1:bay 2, SAS, 146 GB, OK)
array B (SAS, Unused Space: 0 MB)
logicaldrive 2 (1.8 TB, RAID 5, OK)
physicaldrive 1I:1:5 (port 1I:box 1:bay 5, SAS, 500 GB, OK)
physicaldrive 1I:1:6 (port 1I:box 1:bay 6, SAS, 500 GB, OK)
physicaldrive 1I:1:7 (port 1I:box 1:bay 7, SAS, 500 GB, OK)
physicaldrive 2I:1:3 (port 2I:box 1:bay 3, SAS, 500 GB, OK)
physicaldrive 2I:1:4 (port 2I:box 1:bay 4, SAS, 500 GB, OK)
physicaldrive 1I:1:8 (port 1I:box 1:bay 8, SAS, 500 GB, OK, spare)
[...]
After that I could create the filesystem on It, mount It and use It without any issue.
My problem is that One week later the controller still was initializing parity.
[...]
Array: B
Interface Type: SAS
Unused Space: 0 MB
Status: OK
Logical Drive: 2
Size: 1.8 TB
Fault Tolerance: RAID 5
Heads: 255
Sectors Per Track: 32
Cylinders: 65535
Stripe Size: 64 KB
Status: OK
Array Accelerator: Enabled
Parity Initialization Status: In Progress
Unique Identifier: 600508B10010443953554B484250000C
Disk Name: /dev/cciss/c0d1
Mount Points: /buzonesdir 1.8 TB
OS Status: LOCKED
Logical Drive Label: A0C36F2EP61620D9SUKHBPA42A
[...]
At that moment, trying to speed up the parity initialization, I increased the rebuild and expand priority from "medium" to "high".
But, one week later (working with high priority) the "Parity Initialization Status" is still "In Progress".
Do you know if this is normal and I should let It continue working?
Do you know any way to check if really "Parity initialization" is being done and how long It will last?
Thank you very much.

Re: "Parity Initialization Status: In Progress" for long time
hi,
Please update the FW of the controller - the latest version is 7.22 and please try putting a file on the logical drive and check what happens.
Thanks!
regards,

Re: "Parity Initialization Status: In Progress" for long time
I've a similar chase where we have a 6 member RAID 6 logical drive that we have created on Monday is still in
"Parity Initialization Status: In Progress" mode on Friday:
array B (SAS, Unused Space: 0 MB)
logicaldrive 2 (273.3 GB, RAID 6 (ADG), OK)
physicaldrive 1I:1:5 (port 1I:box 1:bay 5, SAS, 72 GB, OK)
physicaldrive 1I:1:6 (port 1I:box 1:bay 6, SAS, 72 GB, OK)
physicaldrive 1I:1:7 (port 1I:box 1:bay 7, SAS, 72 GB, OK)
physicaldrive 1I:1:8 (port 1I:box 1:bay 8, SAS, 72 GB, OK)
physicaldrive 2I:1:3 (port 2I:box 1:bay 3, SAS, 72 GB, OK)
physicaldrive 2I:1:4 (port 2I:box 1:bay 4, SAS, 72 GB, OK)
The controller and disk are on latest FW and the Rebuild Priority is set to High:
Smart Array P400 in Slot 1
Bus Interface: PCI
Slot: 1
Serial Number: PAFGK0K9VW22GP
Cache Serial Number: PA2270J9SW55EZ
RAID 6 (ADG) Status: Enabled
Controller Status: OK
Chassis Slot:
Hardware Revision: Rev E
Firmware Version: 7.24
Rebuild Priority: High
Expand Priority: Medium
Surface Scan Delay: 15 sec
Cache Board Present: True
Cache Status: OK
Accelerator Ratio: 50% Read / 50% Write
Drive Write Cache: Enabled
Total Cache Size: 512 MB
Battery Pack Count: 1
Battery Status: OK
SATA NCQ Supported: True
The ADU Report is attached.
Since we could not wait on Monday for the parity initialization to complete so we restored and are running an Oracle Database on it (without any issues so far).
How long does it usually take to build up such a RAID Volume?
Thanks much for all hints & best Regards,
Arnold

Re: "Parity Initialization Status: In Progress" for long time
I checked the status today and found out that it eventually completed:
# hpacucli controller slot=1 ld 2 show detail
Smart Array P400 in Slot 1
array B
Logical Drive: 2
Size: 273.3 GB
Fault Tolerance: RAID 6 (ADG)
Heads: 255
Sectors Per Track: 32
Cylinders: 65535
Stripe Size: 16 KB
Status: OK
Array Accelerator: Enabled
Parity Initialization Status: Initialization Completed
Unique Identifier: 600508B100104B395657323247500004
Disk Name: /dev/cciss/c0d1
Mount Points: None
Logical Drive Label: A01E2AD0PAFGK0K9VW22GPDF51
So, depending on the environment, expect this to take some weeks!
Best Regards,
Arnold

Re: "Parity Initialization Status: In Progress" for long time
Mine also finally finished successfully.
After several weeks the task was finally completed. It took an incredible amount of time but finally finished well.

Re: "Parity Initialization Status: In Progress" for long time
Hi Guys thank you for this page.
But isn't it crazy that it took you several weeks
I tried a lot of stuff
hpssacli controller slot=0 modify rebuildpriority=high
hpssacli controller slot=0 modify ssd=0
But this LD is still uner
Parity Initialization Status: In Progress after days.
Fyi it is only a Raid5 with 4x300GB (yes yes I know Raid5 is bad and I should feel bad)
Thanks a lot,
Sonny
edit 1 : BTW If you know how to check the progress of "Parity Initialization Status" (in % or else) Do not hesitate to tell me

Re: "Parity Initialization Status: In Progress" for long time
I found out this progress can be viewed in the HPE Smart Storage Administrator (for Windows at least), and the process priority is defined by the Surface Scan Priority setting of the Array Controller. By default it is set to 'idle' which means it only performs parity initialization when the controller/disks are idle (on a server this is likely to be not very often). Set it to high to work faster.
I know because after 3x days mine was still at 0.00%, and then when I changed this setting it immediately started going up, and after about 8hrs it was complete.

Thanks, that worked.
With hpssacli utility: hpssacli ctrl slot=0 modify surfacescanmode=high
