Notes on Hard Drive Maintenance

•

•

Hot-swappable drive trays: The drive trays are all hot-swappable. If a hard drive fails, it can be replaced while the subsystem is still running.

Forearm handles: If the hard drive is behind either the left or right forearm handle, make sure that the locking mechanism on the side of the handle is first released prior to open- ing the handle itself. (See Figure 6.7) The locking mechanism must also be released in order to close the handle. Therefore, after the new drive has been installed, it will be nec- essary to release the locking mechanism on the handle prior to closing it.

Front flap mechanism: Do not leave a drive tray’s front flap open. The front flap and its key-lock secure a drive tray to chassis slot. A disk drive operating with the half-open front bezel may result in signal glitches and Data Compare Errors might ensue.

Remove drives slowly: Although the drive trays are designed to be hot-swappable, when removing a drive tray from the subsystem, withdraw it from the chassis slowly. Removing the drive tray too quickly may cause a drive I/O timeout.

Replacement on hand: If a hard drive has failed, make sure you have a replacement hard drive readily available before removing the failed drive from the subsystem. Do not leave the drive tray slot open for an extended period of time. If the drive tray slot is left unoccu- pied for an extended period of time, the airflow will be disrupted and subsystem compo- nents will overheat and may be permanently damaged.

6.7.2Replacing a Failed Hard Drive

To replace a hard drive, please follow these steps:

CAUTION!

•

•

•

Handle hard drives with extreme care. Hard drives are very delicate. Dropping a drive onto a hard surface (even from a short distance) and hitting or touching the circuits on the drives with your tools may all cause damage to drives.

Observe all ESD prevention methods when handling hard drives.

Only use screws supplied with the drive canisters. Longer screws may damage the drive.

CAUTION!

The hard drives and drive trays should only be installed into the subsystem once the subsys- tem has been mounted into a rack cabinet. If the hard drives are installed first, the subsystem will be too heavy to place into position and the possible impact during installation may dam- age your drives.
