Finding Controller, Storage Expansion Enclosure, And Drive Information - IBM System Storage DS4000 EXP420 Installation, User And Maintenance Instructions

DS4000 controller firmware, the hard drive firmware, and the NVSRAM (for
controllers only) must be up-to-date. Go to the following Web site to get the latest
updates:
www.ibm.com/servers/storage/support/disk/
Refer to "Software and hardware compatibility and upgrades" on page 9 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
Storage Manager software updates or any important information about your DS4000
subsystems (see "Product updates and support notifications" on page 12).
Attention:
Storage 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 DS4000 readme files" on page xxiii 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 and ATA translator card 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 enclosure 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 DS4000
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.
