Table 1 Supported Trays and Software Upgrade Paths
NOTE If you are upgrading from controller firmware version 7.75.26, you must first
upgrade to 7.75.28, and then upgrade to 7.86. All other supported upgrades are
performed directly without an intermediate step.

Management
Software,
Firmware, and
NVSRAM
NOTE To make sure that your failover driver is compatible with the new hardware,
firmware, and software, refer to the SANtricity ES Storage Manager Failover Drivers
User Guide for Version 10.86. For the RHEL and SLES operating systems, if you are
setting up a configuration to support Asymmetric Logical Unit Access (ALUA),
additional steps are required to set the correct Operating System in Storage Partition
Mapping.
These steps are required for a successful upgrade to storage management software
version 10.86 and controller firmware version 7.86. Perform the steps in order.
1. Make sure that the controller-drive trays in your storage array are compatible
with the software level and the firmware level to which you are upgrading.
2. Check that the host bus adapters (HBAs), switches, driver versions, firmware
levels, and specific hardware restrictions are supported.
Refer to your storage vendor for compatibility information.
NOTE If you plan to upgrade or install storage area network (SAN) hardware, make
those changes before you upgrade the storage management software.
3. Start the existing storage management software with the procedure for your
operating system.
4. Check that the storage array has Optimal status.
