Recovering a VMWare Datastore after
upgrading/downgrading FW on select Cisco RAID
Controllers

Introduction

This document's intent is to address the issue of the loss of VMWare Datastores upon
downgrading Firmware (FW) on select Cisco RAID Controllers.

The issue affects any combination of the following Cisco Hardware/Software:

Servers:

UCSC-C3160, UCSC-C220-M4s, UCSC-C220-M4L, UCSC-C240-M4S, UCSC-C240-M4SX,
UCSC-C240-M4S2, UCSC-C240-M4L, UCSC-C22-M3S, UCSC-C22-M3L, UCSC-C24-M3S,
UCSC-C24-M3S2, UCSC-C24-M3L, UCSC-C460-M4

Storage Controllers:

UCS-RAID-9266-8i, UCS-RAID-9266CV-8i, UCS-RAID-9271-8i, UCS-RAID-9271CV-8i, UCS-
RAID-9285CV-E, UCS-RAID-9286CV-8E, UCSC-MRAID-12G, UCSC-MRAID12G-512, UCSC-
MRAID12G-1GB, UCSC-MRAID12G-2GB, UCSC-MRAID12G-4GB, UCSC-SAS9300-8E, UCSC-
C3X60-R4GB, UCSC-C3X60-HBA, UCSC-C3X60-R1GB

Chassis Firmware:

This issue effects customers attempting to downgrade from release 2.0(4) or later to 2.0(3) or
earlier. This will also affect select customers who upgrade to firmware versions that have not yet
been patched (upgrades from 2.0(3) and earlier to 2.0(6f) and earlier).

Note: The upgrade only affects customers with a combination of C220/C240 M3 servers and
9271CV-8i/9271-8i based Raid Controllers.

Customer Visibility/Impact: Customers may see VMWare datastores become lost after the
particular FW upgrade/downgrade. This will not affect VMWare boot drives. In VSphere client, the
datastore status may look like this:
