Host and Storage Usage
Eventlog and Host Log Messages
All HP 3PAR system debug messages can be seen using the showeventlog
•If the user has set the space allocation warning for a TPVV volume, the system eventlog will show the Thin provisioning soft threshold reached message when the limit is hit.
Example:
1 DebugHost error undefined Port 1:5:2
WWN:50002ac00264011c VV:0 CDB:280000AB082000000800 (Read10) Skey:0x06 (Unit attention) asc/q:0x38/07 (Thin provisioning soft threshold reached) VVstat:0x00
(TE_PASS | |
lunerr:2 |
|
•If the user has set a hard limit on the HP 3PAR StoreServ Storage volume when using HP 3PAR OS 2.3.1 MU2 or later, the HP 3PAR StoreServ Storage will post the write protect error (ASC/Q: 0x27/0x7) when the limit is reached. This is considered a hard error, and the VM is stunned in ESX 4.x and ESXi 5.x. Additional space needs to be added to the storage to clear the error condition.
