Chapter 1: Preparing to Upgrade Your Storage Management Software 3

13. Check that the storage array has an Optimal status. If one or more managed

devices has a Needs Attention status, contact your Technical Support

representative.

14. If you determined from the storage array profile that the NVSRAM firmware, the

controller firmware, or the ESM firmware is not the current version, download

the compatible firmware.

NOTE With the I/O Shipping feature, a storage array can use asymmetric logical unit

access (ALUA). ALUA enables a controller tray or a controller-drive tray to service

I/O requests through either controller in a duplex configuration. To use the I/O

Shipping feature with VMware, you must take additional steps to update the VMware

configuration. See Upgrade Instructions for Asymmetric Logical Unit Access (ALUA)

with the VMware OS on page 139 for instructions.
