additional disk space is added, use the Retry option on the warning message to bring the VM back to the read-write state. If you select the Cancel option, the VM is rebooted.

In the following example, an HP 3PAR StoreServ Storage TPVV volume was created with a warning limit of 60%, as shown in the showvv -alertcommand.

When the warning limit is reached, the HP 3PAR StoreServ Storage sends a soft threshold error asc/q: 0x38/0x7 and ESX continues to write.

InServ debug log:

When the HP 3PAR StoreServ Storage runs out of disk space, a hard permanent error asc/q: 0x27/0x7 is sent. Use showspace, showvv -r, and showalert to see the warning and space usage. The ESX responds by stunning the VM.
