All unlit Check for and resolve one of the following situations:
v
EXP100 is turned off
v
EXP100 is not connected to the DS4000
v
DS4000 does not have the correct firmware version
v Fibre-channel loop IDs: When you install a hard disk drive in the expansion
enclosure, the drive tray connects into a printed circuit board called the midplane .
The midplane sets the Fibre Channel loop ID automatically, based on the setting
of the enclosure ID switch and the physical location (bay) of the drive CRU.
v Hot-swap hardware: The EXP100 contains hardware that enables you to
replace a failed hard disk drive without turning off the expansion enclosure. You
can continue to operate your system while a hard disk drive is removed or
installed. These drives are known as hot-swap hard disk drives.
Notes for installing the new 250 GB SATA drive CRU/FRU (P/N
40K6837)
The 250 GB SATA CRU P/N 90P1349 is being replaced by CRU P/N 40K6837,
which requires a certain minimum level of the DS4000 storage subsystem controller
firmware and the EXP100 drive expansion enclosure ESM firmware.
Prior to installing the hard drive in your DS4000 configuration, your DS4000 storage
subsystem firmware must be at the required versions. If a firmware upgrade is
required to install the new drive CRU/FRU, complete one of the following actions
according to the state of your DS4000 storage subsystem:
1. DS4000 storage subsystem in Optimal state: Upgrade to the latest firmware
version that is required to maintain this minimum level for your DS4000 storage
subsystem. To download the latest firmware, go to the IBM DS4000
TotalStorage Support Web site, and then click on the appropriate link for each of
your DS4000 storage subsystems:
www.ibm.com/servers/storage/support/disk/
2. DS4000 storage subsystem in Needs Attention state: Contact your IBM
support representative for additional instructions.
Important: If you are installing P/N 90P1349, IBM recommends that you update
immediately to the latest levels of firmware that support the new 250 GB SATA CRU
(P/N 40K6837). If upgrading firmware after installing the 250 GB CRU P/N
90P1349, upgrade to the latest firmware version required to maintain this minimum
level for your DS4000 storage subsystem. To download the latest firmware, go to
the IBM DS4000 TotalStorage support Web site (listed above).
Installing hot-swap hard disk drives
You can install hard disk drives while the expansion enclosure is turned on and
running.
Important: If you are installing the new 250 GB SATA drive CRU/FRU (P/N
40K6837), read the information in “Notes for installing the new 250 GB SATA drive
CRU/FRU (P/N 40K6837)” before you perform this procedure.
