Attention:
1. After you remove a drive from a bay, wait 70 seconds to allow the drive to spin
down before you replace or reseat the drive. Failure to do so might cause
unpredictable results.
2. Never hot-swap a drive when its associated green activity LED is flashing or its
associated amber fault LED is flashing. Hot-swap a drive only when its
associated amber fault LED is lit continuously or when the drive is inactive and
its associated green activity LED is not flashing.
Note: If the hard disk drive that you want to remove is not in a failed or bypass
state, always use the Storage Manager software either to place the drive in a
failed state or to place the array that is associated with the drive (or drives)
in an offline state before you remove the drive from the enclosure.
Controllers
The DS3300 has one or two hot-swappable and redundant RAID controllers. The
controllers are at the rear of the storage subsystem. The left controller is controller
A, and the right controller is controller B. When the DS3300 has two controllers,
one controller will continue to operate if the other controller fails.
The controllers contain the storage subsystem control logic, interface ports, two
gigabyte iSCSI data ports, and LEDs.
Each controller has one drive expansion port for connecting to the DS3000 storage
expansion enclosures and one Ethernet port for DS3300 subsystem management
purposes. See Figure 13 on page 23 and Figure 20 on page 34.
Attention: When a DS3300 has two controllers, the controllers must be identical
to each other in hardware (part number, DIMM size) and firmware.
The storage management software automatically sets the enclosure ID number for
the controllers. You can change the enclosure ID setting through the DS3000
storage management software only. There are no switches on the DS3300 chassis
to manually set the enclosure ID. Both controller enclosure ID numbers are identical
under normal operating conditions.
