Go to SolutionReclaim space from offline/decommissoned server
Okay, now I need to reclaim the storage from an offline/decommissoned server. I know the space is still reserved somewhere out there, even though the Symmetrix database says there's no devices attached to that server anymore.
First, the evidence:
| [# symmask list logins |
| Symmetrix ID | : xxxxxxxxxxxx28 |
Director Identification : FA-8D
| Director Port | : 0 |
| User-generated | Logged On | |||
| Identifier | Type Node Name | Port Name | FCID In | Fabric |
---------------- ----- --------------------------------- ------ ------ ------
| 50060b0000111120 Fibre tan | td2 | b20100 Yes | Yes |
Director Identification : FA-9D Director Port : 0 User-generated Logged On Identifier Type Node Name Port Name FCID In Fabric ---------------- ----- --------------------------------- ------ ------ ------ 50060b0000c99a86 Fibre tan fcd0 4a0400 Yes Yes |
I believe device 0060 was masked and attached to this server. Why? Because I can't find 0060 attached to anything else on FA 8D:0 & 9D:0:
# symmaskdb list assignment -dev 0060
No device masking database records could be found for the specified input parameters
| # symdev list -v -dev 0060 | more |

Device 0060 is just one example. Is there anyway to reclaim this device so that I can "unmeta" it and return the devices back to the pool? And is there anyway to identify other devices that were attached to the server which went offline and got decommissoned before I could return the space back to the pool?
Thanks.
