system components. After power is restored, call your IBM technical-support
representative if any of the following conditions occur:
– The storage subsystem logical drives and subsystems are not displayed in the
DS3000 Storage Manager Version 2 graphical user interface.
– The storage subsystem logical drives and subsystems do not come online.
– The storage subsystem logical drives and subsystems seem to be degraded.
Storage subsystem components
The storage subsystem has the following removable components. These
components, called customer replaceable units (CRUs), are accessible from the
front or rear of the storage subsystem.
v
Up to twelve 3 Gbps SAS or SATA hard disk drives
v Up to two RAID controllers
v
Two power supplies
Disk drives and bezels
Figure 2 shows the locations of hot-swap disk drives and bezels. The hot-swap
features enable you to remove and replace hard disk drives, power supplies, and
controllers (in a dual-controller storage subsystem) without turning off the storage
subsystem. You can maintain the availability of the storage subsystem while you
remove, install, or replace a hot-swap device.
The hot-swap drive bays that are accessible from the front of the storage
subsystem are shown in Figure 2.
Hot-swap hard disk drive
You can install up to 12 hot-swap SAS or SATA hard disk drives in the
DS33000.
Filler panel
The DS3300 comes with filler panels in the drive bays. Before you install a
hard disk drive, remove the filler panel and save it for future use. Each of
the 12 drive bays must contain either a filler panel or a hard disk drive.
