1 Upgrading HP LeftHand Storage HP recommends that you always upgrade to the latest version of the HP LeftHand Storage including: • Firmware • SAN/iQ • CMC • CLI • DSM for MPIO • Application Aware Snapshot Manager Beginning with Version 9.0, the CMC enables online upgrades for HP LeftHand Storage. Use the CMC to check for, download, and install the latest versions and patches. You can also use the latest CMC to manage storage systems, management groups, and clusters that are running earlier versions of SAN/iQ. For example, a Version 9.5.x CMC will manage clusters of storage systems running Version 9.0 SAN/iQ. NOTE: Online upgrade is only available for firmware, SAN/iQ, and the CMC. For all other components, the CMC will indicate what version you should upgrade to (based on the current SAN/iQ version or the SAN/iQ version you are upgrading to). Upgrade planning Review Table 1 (page 4) to ensure you are prepared to upgrade your storage systems and SAN. Table 1 Upgrade planning checklist Task Description Verify the software version you are currently running and the upgrade path to the new release software. See "Supported upgrade paths" in the latest HP LeftHand Storage Release Notes to determine if there is a direct upgrade path for your storage systems, or if you have to upgrade to an 8.x version before upgrading to the current version. Verify the health of the storage systems and management groups. Ensure that all storage systems are in a good state with no critical events. If you are using management groups, ensure that: • You are logged in to the management groups you want to upgrade. • At least two storage systems are running managers, so you do not lose quorum. See "Managers and quorum" in the HP LeftHand Storage User Guide. • All virtual managers in the management group are stopped.See "Stopping a virtual manager" in the HP LeftHand Storage User Guide.
