You must update to v9.0 first, and then from v9.0 to v9.1. • If you are updating from a version earlier than v6.0.x, contact Dell Technical Support for assistance. General Rules Unless otherwise indicated, the following rules apply when updating array firmware: • 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 firmware 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 firmware 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 firmware. For example, to update a group from version 8.1.2 to version 9.1, you must first update to version 9.0, then to version 9.1. See Supported Update Paths for version-specific limitations. Known Limitations and Recommendations The following known limitations and recommendations apply when updating firmware 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 firmware. • Disable all the collection replication schedules. • Verify that all in-progress replication operations have completed before updating the member.
