If you are planning to add a new host to your storage, add expansions, change HBAs in your
hosts, or perform other hardware configuration changes, check for the latest supported
combinations at the following Web site:

This replaces the older compatibility matrix PFD files.
7.1.3 Planning for upgrades
Upgrading the firmware and management software for the DS5000 storage subsystem is a
relatively simple procedure, but some preparation and caution are needed to ensure a
smooth upgrade.
Check the Dependencies section for further details.The components that typically need to be
updated are:
Storage Manager software
Controller firmware
NVSRAM firmware
ESM firmware
Disk drives firmware
Upgrading large storage configurations can be time consuming. Time estimates for upgrading
all the associated firmware and software are listed in Table 7-1.
Table 7-1 Upgrade times
These times were observed in the lab. They are approximate and might vary from system to
system. When activating controller firmware or NVSRAM, the maximum times are 15 minutes
per controller.
Important: Always check the readme files of the firmware you are going to install for
prerequisites before proceed with the update.
Attention: Users upgrading from 6.xx.xx.xx controller firmware must upgrade to 7.1x.xx.xx
or 7.36.xx.xx firmware first before upgrading to 7.50.13.00 or above.
Note: Always make a backup of data before you start an upgrade.
Element being upgraded Approximate time of upgrade
Storage Manager and associated drivers and
utilities
35 minutes
ESM firmware 5 minutes per ESM
DS5000 storage subsystem firmware and
NVSRAM
5 to 35 minutes
Hard drives 2 minutes per drive (but it is possible to do a
parallel firmware upgrade, even for multiple drive
types)
