Chapter 5. Installing and replacing components This chapter provides instructions to help you install or remove customer replaceable units (CRUs), such as hot-swap drives, fans, RAID controllers, and power supplies. This chapter also provides instructions to help you add new DS4000 EXP100 expansion units to existing DS4100 configuration. For more C[...]

Attention: After you remove a drive CRU, wait at least 70 seconds before replacing or reseating the drive CRU to allow the drive to properly spin down. Failure to do so may cause undesired events. Before you install or remove drive CRUs, review the following information: v Blank trays: A storage server without a full set of drives (14) contains bla[...]

1. Read the documentation that comes with the hard disk drive. 2. Check for Fault LEDs shown in Figure 62. If any amber LEDs are lit, see Chapter 6, “Hardware maintenance,” on page 111 . 3.

Yo u must use this method on RAID 0 logical drives. v Replacing the drives one at a time In this method, you manually fail each drive, replace it, and wait for the system to restore data to the new drive before installing the next drive[...]

2. Use the DS4000 Storage Manager client to check the status of the storage server . Correct any problems that are reported. 3. Perform a complete backup of the drives that you are replacing. Yo u need the backup to restore data on the drives later in this procedure. Attention: When you handle static-sensitive devices, take precautions to avoid dam[...]

Unpredictable results can occur when nonmatching controller CRUs are present in the same DS4100 chassis. v After the new controller in a DS4100 single-controller storage server completes the boot process, its WWNN will change. If you have any applications that rely on the previous WWNNs, such as fibre channel [...]

Replacing a RAID controller When instructed to do so by the DS4000 Storage Manager client, replace a RAID controller that has failed. The procedure for replacing a failed controller is different for DS4100 single-controller and base (dual-controller) storage servers. If a controller in a DS4100 base storage server fails, you can replace the failed [...]

Note: Avoid operating the DS4100 with controllers of dif ferent cache sizes. Operating the storage server with controllers of different cache size will disable caching and might adversely affect performance. Always verify that you replace a failed controller with a controller that has the same FRU part number . To replace a RAID controller , perfor[...]

Note: The preferred method of checking for the battery operating age is through the storage server management software. 19. Position the battery inside the replacement RAID controller . 20. Reassemble the battery access panel to the RAID controller bottom[...]

The startup process should complete within five minutes. After the startup process completes, the new RAID controller can accept I/Os from the host server and is ready to be managed by the DS4000 Storage Manager client. Note: If the new RAID controller is not recognized by the DS4000 Storage Manager client, use the Enterprise Management Window to r[...]
