Solution 1909550.1 : How to Recover Failed Logical Drives on a HP MSA ?

Applies to:

Oracle Communications Performance Intelligence Center (PIC) Software - Version 6.6.4 and later
Information in this document applies to any platform.

Goal

In some cases (for example when a power outage occurs or when the server/MSA connection is severed) the Logical Drives configured on the MSA may end up in FAILED state.

This document explains how to re-enabled FAILED logical volumes on a MSA.

Solution

The FAILED state will prevent the operating system from writing data on the partition located on the logical drives.

To fix this, you must first re-enable the logical drives. As root user login to hpacucli utility.

Log as root on server
Start HP utility:

hpacucli
Show logical drive status:

=> ctrl slot=2 ld all show status
Expected output:

logicaldrive 1 (1.6 TB, RAID 5): Failed
logicaldrive 2 (1.6 TB, RAID 5): Failed
re-enable logical drive:

=> ctrl slot=2 ld 1 modify reenable forced
=> ctrl slot=2 ld 2 modify reenable forced
Check logical drive status is OK:

logicaldrive 1 (1.6 TB, RAID 5): OK
logicaldrive 2 (1.6 TB, RAID 5): OK

Depending on hardware type, the controller slot and logical drive number may vary.

Once the Logical drives are re-enabled, try to write data on the partition hosted by these Logical drives, if the write still fails then reboot the server.
