Maintenance and Service Guide
Upgrading the software image
This section describes the supported upgrade methods and procedures required to
successfully upgrade the array controller ACS firmware from V8.6-x or V8.7-x to
V8.8-x. ACS V8.8-x supports both dual-redundant controller rolling upgrade and
dual-redundant controller shutdown upgrade methods. The rolling upgrade
method allows the host system to continue I/O activity, with minimal impact,
while each controller is upgraded. The shutdown upgrade method takes the
storage devices offline for a period of time while the software is upgraded
simultaneously on both controllers.
Caution: Failure to follow these upgrade procedures can result in the loss of
data, or the controller can be left in an unusable state. Completely read and
understand all of the required steps prior to upgrading.
Do not
use the procedures in this guide in an attempt to upgrade from ACS
V8.4 or 8.5 (or any other unsupported version) to ACS V8.8-
x
. Significant
downtime and data loss can result.
