GUI Firmware Update Does Not Work in an Environment Running Only IPv6
The PS Series group must have IPv4 addresses to use the GUI update procedure. If your group uses an IPv6 address, follow the
steps listed under Update the PS Series Firmware Using the CLI.
Use the CLI to Update Firmware in a Single Controller Environment
The Firmware Update Wizard displays the error Single controller updates are not allowed from the GUI in the
Group Manager GUI when the array module being updated has only a single control module. In a single controller environment, you
must perform the update using the CLI.
Updating Firmware Not Allowed from GUI when FTP is Disabled
Firmware updates cannot be performed using the Group Manager GUI when FTP is disabled. To update array rmware for groups in
which FTP has been disabled, use the CLI instead.
Working With Multimember Groups
A PS Series group includes one or more PS Series storage arrays congured as group members. Dell recommends that all PS Series
group members run the same version of the storage array rmware; in multiversion congurations, the group can support only the
functionality that is common to all versions.
Add a New Array to an Existing Group
If you are adding a new array to an existing group, consider updating the group to the latest rmware before adding the new member
to the group.
NOTE: In general, mixed rmware groups are supported only during the period of time during which you are updating all
members. See Supported Update Paths for information about specic rmware releases.
Update Across Multiple Releases
If you must update to an interim version, update all the members to the interim version, then update all the members to the nal
version. Between updating group members, wait for the SAN to stabilize before continuing with the update. Use the Group Manager
GUI or CLI to make sure that all members and volumes are online. Also, make sure that iSCSI initiators reconnect to volumes (if
applicable).
Important Information About Dell EqualLogic Firmware Updates and Microsoft Windows
Clusters
Before you execute a Dell EqualLogic rmware update, to prevent potential conicts between the SAN infrastructure and cluster
follow the requirements and recommendations described in the following section:
Microsoft Windows 2012 or 2016 Server Cluster
Place the Windows 2012 or 2016 cluster in maintenance mode during a SAN infrastructure rmware update. The average storage
array restart time ranges from 15 seconds to several minutes, depending on your specic conguration.
Dell strongly recommends taking the following actions:
• Ensure that all cluster nodes are running the latest Microsoft updates, patches, and service pack levels prior to performing a SAN
infrastructure rmware update.
• Update all cluster nodes to the latest Host Integration Tools (HIT kit) prior to performing a SAN infrastructure rmware update.
