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
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 DS3200 has one or two
The controllers contain the storage subsystem control logic, interface ports, and LEDs. A
A
Each controller has one SAS drive expansion port for connecting to the DS3000 storage expansion enclosures and one Ethernet port for DS3200 subsystem management purposes. See Figure 13 on page 23 and Figure 23 on page 35.
Attention: When a DS3200 has two controllers, the controllers must be identical to each other in hardware (part number, DIMM size) and firmware. If you install a SAS host port adapter in either controller, you must install an identical SAS host port adapter in the other controller.
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 DS3200 chassis to manually set the enclosure ID. Both controller enclosure ID numbers are identical under normal operating conditions.
