Updating MSA controller ﬁrmware

CAUTION:

The following methods are available for updating MSA array or storage enclosure ﬁrmware; select

the method that best matches your environment:

• Updating MSA ﬁrmware using the SMU

• Updating MSA ﬁrmware using the MSA-CLI (most environments)

Prerequisites

Before updating system ﬁrmware,makenoteofthefollowing:

• When determining which MSA controller ﬁrmware version to use, review the requirements and

information in the Compatibility Matrix(es), release notes, and other MSA announcements.

• Because ﬁrmware updates require least one restart of the MSA array and its attached storage

enclosures, update system ﬁrmware only during a scheduled maintenance window.

• Before updating system ﬁrmware, stop all host trafﬁc to the array controller.

• Before updating system ﬁrmware, make sure that a recent, known good backup of all data on

the MSA array is available.

• Before updating system ﬁrmware,makesurethatacopyoftheconﬁguration, including the iSCSI

IP addressing and portal information, along with the hard drive, LUN, and target information is

available.

• If it has been more than six months since you restarted your MSA storage system, HP recommends

that you power-cycle the MSA (power off, and then power on) before updating the ﬁrmware to

ensure that you are working with a fresh system.

• For newly installed MSA, do not perform a ﬁrmware update until controller batteries are fully

charged.

• For an existing MSA, do not perform a ﬁrmware update until you have conﬁrmed that the “host

mode” or “proﬁle” for each connection is correctly set. The host mode identiﬁes the operating

system of each connection to the storage. Do not use the “default” setting. If the host mode is

not properly set, hosts may lose access to the storage or experience other difﬁculties after the

update. Depending on your operating system environment or user preference, the host mode is

set through the “connection” commands of the CLI or through the “ACL” settings of the SMU. For

more information, see the CLI or SMU user documents.

• In dual-controller MSA1510i conﬁgurations, you MUST log off all redundant paths to the MSA

array prior to beginning a ﬁrmware update. The update will not succeed if redundant paths are

detected by the MPIO/DSM and may require multiple reboots to recover back to the original

ﬁrmware version. There could also be potential loss of connection of the Internet Explorer to the

management port if there are redundant paths during the ﬂash update cycle.

• In dual-controller MSA1510i conﬁgurations, only one of the two MSA controllers is updated

directly. The second MSA controller is updated (cloned) when the MSA is power-cycled after

completing the update of the ﬁrst controller.

• Depending on the storage enclosure model attached to the MSA array (SATA or SCSI), you may

be able to update enclosure ﬁrmware or hard drive ﬁrmware through the MSA utility.

• After the update is complete, be sure to check the status of the MSA for unexpected issues.

After power-cycling the MSA array, verify the status of the connections, deﬁned proﬁle types,

redundancy settings, and storage conﬁguration.

• After the update is complete, power cycle the MSA and all of its attached hard drive storage

enclosures to activate the new ﬁ

rmware.
