NOTE:

An error always generates a condition report. Not all condition reports are generated by errors.

Error condition categories

Each error condition is assigned to a category based on its impact on disk enclosure operation. The

following four error categories are used:

• Unrecoverable—themostsevereerrorcondition,itoccurswhenoneormoreenclosure

components have failed and have disabled some enclosure functions. The enclosure may be

incapable of correcting, or bypassing the failure, and requires repairs to correct the error.

NOTE:

To maintain data integrity, corrective action should be implemented immediately for an

UNRECOVERABLE condition.

• Critical—occurs when one or more enclosure components have failed or are operating outside

of their speciﬁcations. The failures i mpact the normal operation of some components in the

enclosure. Other components within the enclosure may b e able to continue normal operations.

Prompt corrective action should be taken to prevent system degradation.

• N oncritical—occurs when one or more components inside the enclosure have failed or are

operating outside of their speciﬁcations. The failure of these components does not impact

continued normal operation of the enclosure. All components in the enclosure continue to

operate according to their speciﬁcations. The ability of the c omponents to operate correctly

may be reduced should other errors occur. Prompt corrective action should be taken to prevent

system degradation.

• Information—the least severe condition indicates a condition exists tha t does not reduce the

capability of a component. H owever, the condition can become an error and require corrective

action. An INFORMATION condition provides an early warning, which enables you to prepare

to implement corrective action before a component fails. Correction of the reported problem

may be delayed.

The error conditions are prioritized by severity—from most severe to least. The most sev ere condition

takes precedence and is reported ﬁrst when multiple errors are detected. The reporting characteristics

for each error condition are listed in Table 18.

Error queue

The EMU maintains an internal error queue for storing error conditions. Each error cond ition remains in

the error queue until the problem is corrected, or for at least 15 seconds after the error is reported. This

ensur

es that when there are multiple errors or a recurring error, each can b e displayed. Each entry in the

error

queue can be displayed using a combination of the top and bottom buttons. Each error entry in the

queue contains the element type, the element num b er, and the error code.
