Description (partial)

UCS B/C Series M4 based servers with MRAID12 RAID controllers may intermittently crash or hang. 

Other symptoms:
-ESXi host will become un-manageable and unusable
- Able to KVM into server, but no control.
- Able to ping CIMC and ESXi mgmt interface
- Able to SSH/putty into ESXi, will take user/password. Once logged in, no control.

The following faults may be seen in UCSM or CIMC:

Critical F1004 'Controller 1 on server 3/4 is inoperable. Reason: Device non-responsive'
Major     F0181   'Local disk 1 on server 3/4 operability: inoperable. Reason: Drive state: unknown'
Major     F0181   'Local disk 2 on server 3/4 operability: inoperable. Reason: Drive state: unknown'

The following driver is seen in ESXi:

# esxcli software vib list | grep lsi


And appears as applied to at least one adapter in:

# esxcfg-scsidevs -a

If adapters use megaraid_sas driver in the above command, you are not affected by this issue

1. MRAID12G based RAID controller in use
2. VMware ESXi 5.5 ISO retrieved from VMware site between 11/12/14 to 1/5/15. Issue has also been observed on 6.0 ISO images
3. RAID driver: lsi-mr3/lsi-msgpt3


1. Prior to removing lsi-mr3/lsi-msgpt3, verify that the correct mega_raid driver is installed.
2. Use command to verify: 'esxcli software vib list'
3. If lsi driver is removed and mega_raid is not already installed, datastore access will be lost as there is no driver for the controller present.
