Figure 1-2 Find the Storage Node Running the VIP • Remote Copy - If you are upgrading management groups with Remote Copy associations, you should upgrade the remote management groups first. If you upgrade the primary group first, Remote Copy may stop working temporarily, until both the primary management group and the remote group have finished upgrading. Upgrade the primary site to 8.5 immediately after upgrading the remote site to 8.5. Refer to How to verify management group version. 1.3.1.1.1 Selecting the Type of Upgrade The release 8.5 CMC supports two methods of upgrades, as shown in Figure 1-3 "Viewing the CMC Upgrade/Installation Window". • One-at-a-time (recommended) - this is the default and only method that should be used if the storage nodes exist in a management group. • Simultaneous (advanced) - this allows you to upgrade multiple storage nodes at the same time if they are not in a management group. Use this only for storage nodes in the Available pool. CAUTION: Do not select "Simultaneous (advanced)" if your storage nodes are in a production cluster. Figure 1-3 Viewing the CMC Upgrade/Installation Window 1.3.1.2 Increase the Size of the OS Disk on the VSAs Due to changes in the size of the VMware tools that get installed during this software upgrade, you must increase the size of the OS disk before upgrading the VSA. Additional space requirements are necessary for future software releases, as well. Therefore, we recommend increasing the size of the OS disk to accommodate both requirements at this time. 1.3 Configuring the P4000 Storage Systems 11
