Event Code Descriptions

Table 14 lists all event codes that can appear in the HP XLR1200/1255 Advanced Disk Array controller log

event pages. The table also includes events that are not logged, but can still generate SCSI sense data.

Appropriate corrective action is included for all events that require it. Many events are informational and

require no action on the part of the user.

The Suspected Component column lists the hardware components potentially implicated by the event code.

In general, the most likely failing component is indicated in the FRU field of the event descriptor.

The

components are listed in decreasing order of likelihood.

Term Definitions

The following terms used in the table may require some clarification:

•

Disk Drive ID Number

this is the unique number assigned by the controller to each disk

drive installed in the array. This number is used by the controller for its internal management

of the disks, and is in no way related to the slot position of the disk drive or to the disk

mechanism’s serial number. The disk drive ID number is frequently used in the component

identifier field of disk system change events to indicate the disk drive involved.

•

Internal SCSI Bus

- This refers to all of the components that comprise the SCSI channel

between the disk array controller and the disk drive. This includes the disk array controller,

the enclosure backplane, and the disk module. In general, the term “back end” refers to the

communication path between the disk array controller and the disk drives.

•

Host SCSI Bus

- This refers to all of the components that comprise the SCSI channel

between the disk array and the host computer. This includes the disk array controller, the

enclosure backplane, external SCSI bus cabling, and components internal to the host

computer (for example, the host SCSI adapter). In general, the term “front end” refers to the

communication path between the disk array controller and the host.

•

SIMM

- A controller NVRAM memory module.
