Before operation 1-1

Hitachi Compute Rack 210H User’s Guide

Before operation

This chapter describes what you should understand before operation.

Avoiding trouble

Bundled Software

1-2 Before operation

Hitachi Compute Rack 210H User’s Guide

Avoiding trouble

This section describes the requirements for daily maintenance in order to avoid

trouble that might occur during system unit operation.

System error check

If some error occurs with the system unit, an error message might be displayed.

To resolve trouble early, verify such alerts immediately.

Hardware errors

Perform error monitoring based on the ERROR LED of the system unit.

See Fault detection on page 2-2 and Operation monitoring on page 2-8

Software errors

Periodically monitor a software error event log. A software error, if one occurs,

is recorded on the event log. For verification of the event log of software

attached to the system unit, see the individual software manuals.

See Bandled software on page 1-5

Consistency check

In a disk array, a re-assign (data migration to a reserved area) is performed if a

bad block (inaccessible area) is detected on the HDD during the read/write

process. However, if a bad block exists in the mirror data part as well as in the

area not accessed for daily operations, no alternation process is performed. If

the HDD fails in such a state, data in the bad block cannot be rebuilt normally and

thus might be lost because mirror data cannot be read.

The disk array of the system unit is equipped with a patrol read function that has

been set to the factory default so it can verify or fix the HDDs periodically.

Therefore, there is no need to conduct a consistency check periodically.
