Trouble Removing a d2600 disk enclosure from SA p812

theBaron — Wed, 22 Aug 2018 13:47:50 GMT

I have a Proliant dl180 G6 with a P812 Smart Controller showing 4 logical devices, running Windows 2008 R2. I have three HP Storagework D2600 disk Enclosures attached to it.

Enclosure A) 12 x 2TB SATA Drives

Enclosure B) 12 x 2TB SATA Drives

Enclosure C) 12 x 2TB SAS Drives

I would like to decommission enclosure B. You'd think it would be a simple matter. I've decommisioned enclosures on other servers without a problem. On this server I'm getting a strange result. When I remove enclosure B from service and bring up the server, the controller, it shows 0 logical drives instead of 3 logical drives. If I go back to the original setup, I get 4 logical drives. When I leave the enclosure B connected and disconnected another enclosure (as a test), the controller shows 0 logical drives. None of the logical drives have anything shared between them (ie. hot spare drives). Why is this happening? How can I fix this? I don't want to screw up the other two enclosures. Thanks, in advance.

Hello,

Couple of questions for you on your configuration from the host side. Do you have MPIO installed correctly? Do you have two paths to the enclosures? Straight thru or redudant cabling? Have you unmapped the LUN/volume on the D2600 you are trying to decommission?

From your description it sounds like you have a software host side issue where the LUNs are interconnected. Did you use the SSA to configure the LUNs or a host based software solution?

However, there is not enough information here to determine your current configuration with all three enclosures connected. You mention there are 4 LUNs yet three enclosures. This inidcates you have at least one enclosure that either has 2 LUNs or you have one LUN that exists across two enclosures. With SATA HDDs in the first two enclosures are you sure you do not have one LUN spanning those two enclosures?

I would urge a backup of your important data before proceeding further. One consideration is to perform the backup delete all the LUNs, remove the enclosure and then you can recreate the LUNs according to your new plans. I understand that is a lot of work but would leave you with a fresh install and remove any issues.

Cheers,

Shawn
