General Rules
Unless otherwise indicated, the following rules apply when updating array rmware:
• You can download the update kit to multiple members simultaneously, but you can restart only one member at a time. For this
reason, Dell discourages updates from multiple simultaneous GUI or CLI sessions.
• You can update rmware to a later release within its own version. For example, you can update version 9.0.1 to any subsequent
version 9.0.x release.
• You can update rmware to the next version. For example, you can update any version 8.1.x release to a version 9.0.x release.
• If you are updating across multiple releases, you might have to update to one or more interim versions before updating to the
latest rmware. For example, to update a group from version 8.1.2 to version 9.1, you must rst update to version 9.0, then to
version 9.1. See Supported Update Paths for version-specic limitations.
Known Limitations and Recommendations
The following known limitations and recommendations apply when updating rmware under certain conditions.
Pause Collection Replications Before Updating Firmware
When planning an update, identify a time period when replication is not occurring. Check all the collection replication schedules.
NOTE: Dell recommends that you not update a PS Series group member while collection replication outbound from the
group is in progress; otherwise, the collection replication operation might fail or appear to hang.
To ensure that no collection replication occurs during an update:
• Make sure that collection replication does not begin while you are updating member rmware.
• Disable all the collection replication schedules.
• Verify that all in-progress replication operations have completed before updating the member.
