Description (partial)

Symptom:
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

lsi-mr3                      
lsi-msgpt3

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

Conditions:
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

CAVEAT: 

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.
