Eventlog and Host Log Messages
All HP 3PAR system debug messages can be seen using the showeventlog -debug cli
command. On the ESX host, errors are reported in /var/log/vmkernel files. Use the showalert
HP 3PAR OS CLI command to see alerts and warnings posted from the HP 3PAR StoreServ Storage.

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.

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.

for LUNs at 5-minute intervals by issuing the REPORT LUN command and discovering any
new LUNs.
