VA7100 newbe help

Bigcountry_1 — Tue, 03 Oct 2006 07:11:15 GMT

I have a VA7100 that appears to have 13 drives.
M/D1 Disk 3HX027NM Good
M/D2 Disk 3HX0N680 Good
M/D3 Disk 3ET06FKN Good
M/D4 Disk 3ET0LR8M Good
M/D5 Disk 3ET0LYNE Good
M/D6 Disk 3ET0NEG5 Good
M/D7 Disk 3ET0L6TH Good
M/D8 Disk 3ET0JZQM Good
M/D9 Disk 3ET0K380 Good
M/D10 Disk 3HX07KRM Good
M/D11 Disk 3ET07NMW Good
M/D12 Disk 3ET0J0XT Good
M/D13 Disk 3ET0656J Good

The redundancy group only has 12 of them in there and one left out, I think?
CAPACITY USAGE

Total Disk Enclosures:________________1

Redundancy Group:_____________________1
Total Disks:________________________12
Total Physical Size:________________400.543 GB
Allocated to Regular LUNs:__________241.009 GB
Allocated as Business Copies:_______0 bytes
Used as Active Hot Spare:___________33.375 GB
Used for Redundancy:________________90.672 GB
Unallocated (Available for LUNs):___35.486 GB

Used by Non-Included Disks:___________33.378 GB

I belive disk 11 is the one left out because it does not have a Redundancy group assigned and it has a disk state of "previously used". I believe that is what is referenced in the above "Used by Non-Included Disks" output. My question is 1, am I correct? 2 what are the steps to add that disk to the redundancy group. I believe I would use armmgr or armcfg?

Thanks for the help.

Hi,

1. The auto include option is off
2. You change it with armmgr -i on/off

Not to argue because I am in no position to argue,but it looks to be on, I think.

The "previously used" disk state indicates that the drive contains information that indicates it was previously being used by another array controller. A user removed the drive from another subsystem and inserted it into this subsystem.

In this case, eventhough the auto-include and autoformat are enabled, the disk won't get added on account of data protection. You need to manually add the disk using armcfg command or SDM GUI.

# armcfg -D M/D11 -a

Check logs using armlog or logprn commands to get more details.

Before adding the disk, I would suggest/recommend to upgrade the firmware of the disk ( currently HP05 )to HP06. This would require downtime. You can get the firmware for the disk model at

http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=en&cc=us&prodNameId=30307&prodTypeId=12169&prodSeriesId=33737&swLang=13&taskId=135&swEnvOID=54

You might also want to upgrade the controller firmware etc to latest ones as mentioned in the link.
