Promise Array Management

Array Critical

When a disk drive fails on a fault-tolerant array (RAID 1, 0+1 and 5) for any

reason, the Array goes Critical. The array can still read and write data but fault

tolerance has been lost.

An Array Critical

icon displays in Tree View and the alarm (if enabled) beeps

quickly to call your attention to the condition.

Figure 72. An Array in Critical condition highlighted in Tree View (left)

and shown in red in Information View (right).

Your first action is to identify which disk drive has failed.

1. Click on the Controller icon to expand it.

2. Click on the Array icon to expand it.

3. Observe and compare the disk drives under the Controller with those under

the Array.

Figure 73. The drives under the Controller should match those under the

Array.

Drives 1, 2 and 3 are assigned

to this array.

Only drives 1 and 3 appear in

the array.

Drive 2 is suspect.
