Refer to "Software and hardware compatibility and upgrades" on page 14 for
software and hardware compatibility information and requirements.
Apply the necessary updates before configuring the storage subsystem arrays and
logical drives. Subscribe to My Support for automatic notifications of firmware or DS
Storage Manager software updates or any important information about your DS4000
subsystems (see "Receiving product updates and support notifications" on page
17).
Attention:
Manager software package for any limitations, subsystem firmware prerequisites, or
download-sequence information. For example, the controller firmware code might
require the storage expansion enclosure ESM firmware to be upgraded first to a
particular version, or the controller firmware download might require the halting of
I/Os to the DS4000's logical drives. Failure to observe the limitations, prerequisites,
and dependencies in the Readme file might result in a loss of data access. See
"Finding Storage Manager software, controller firmware, and README files" on
page xxii to learn how to access the DS4000 readme files on the Web.
Unless the readme file contains special requirements for the sequence in which you
upgrade firmware, you should perform firmware upgrades in the following sequence:
1. ESM firmware for the storage expansion enclosures
2. Controller firmware
3. Controller NVSRAM
4. Drive firmware
Finding controller, storage expansion enclosure, and drive information
You can view a Storage Subsystem Profile to find controller, enclosure, and drive
information for the storage expansion enclosures and DS4000 storage subsystems
to which it is attached. To view a Storage System Profile, perform the following
steps:
1. Open the DS4000 Storage Subsystem Management window from the DS
2. Select Storage Subsystem → View → Profile.
3. Select the Controllers tab.
4. Scroll through the list to find Board ID, Submodel ID, Product ID, and Product
5. Select the Enclosures tab.
6. Scroll through the list to find the Product ID for supported storage expansion
7. Select the Drives tab.
8. Scroll through the list to find the drive values such as Product ID.
Troubleshooting the storage expansion enclosure
The DS Storage Manager is the best way to monitor the storage expansion
enclosure, diagnose a problem, and recover from a hardware failure. You should
run the DS Storage Manager continuously, and check the status of the storage
array frequently.
