System Upgrade 8-5

3.5-INCH HARD DISK DRIVE

The 3.5-inch hard disk drive bay in front of the server contains six slots in which hard disks with the SCA2 interface are installed.

The figures used in this section show the rack-mount model. The orientation is the only difference from the tower model.

IMPORTANT:

Do not use any hard disks that are not authorized by NEC. Installing a third-party hard disk may cause a failure of the server as well as the hard disk. Purchase hard disks of the same model in pair. Contact your sales agent for hard disk drives optimum for your server.

The OS starts from the hard disk that is mounted in Slot 1 of the primary module (whose POWER LED is on).

A SCSI controller error having sraql160 as its source may sometimes be recorded in the system event log. This error is likely to be issued when the hard disk drive processing cannot keep up in time with requests of the OS, but the processing is carried on normally thanks to the retry function. So, this does not affect the operation at all. In case such an error is issued, check the detailed data indicated below, and if it is "f0030004" or "f0030015," just ignore that log.

If, however, a SCSI controller error whose detailed data is "f0030004" or "f0030015" is recorded repeatedly (ten times or more in a week time as a rough guide), a hard disk drive failure is suspected. Contact the maintenance personnel in such a case.

Description:

The driver detected a controller error on \Device\Scsi\sraql160x [x is a numeral as 1 or 2 for example.]

In the case where the detailed data of the above event properties is represented in words, the error represents no trouble if the value from 0034: is “f0030004” or “f0030015”.

TIPS:

POWER LED is on to indicate that it is the primary module.

The module that you plug in first will be the primary module (see Chapter 3).
