Troubleshooting

Problems and solutions

This section contains known problems and solutions.

Problem 1

Error Message ID: 51 — In the event viewer when attempting to

install multiple host access (for clustering) to the same EMC

CLARiiON array storage group. The text of the message reads:

An Error was detected on device \Device\Harddisk<x>\DR<x>

during a paging operation

Solution Until host cluster software is installed, only a single host should

access a storage group at a time. Refer to the EMC Support Matrix for

supported host configurations.

Problem 2

EMC Knowledge base solution emc29097 — If using HBAs connected

to both CLARiiON SPs, without PowerPath installed, duplicate

LUNs will be visible in the Device Manager and Disk Manager. Only

one instance of the LUN will be accessible, and all other matching

mappings will be listed as Unknown, Unreadable, and Unallocated.

Solution This is normal behavior when multiple paths are available,

PowerPath is not installed, and the initiator type is registered in

PowerPath mode (array default depending on core code revision).

Problem 3

EMC Knowledge base solution emc69307 — When using QLogic

HBAs in a Brocade fabric environment, after upgrading Brocade

3900-series switch firmware to 3.0.2m, the HBAs report repeated link

errors, and intermittently lose fabric connectivity.

PowerPath may report paths lost and then found in quick succession,

and repeated Windows 2000 event log error entries for Link

Down/Link Up events similar to the following:

Event ID: 11

Source: ql2300

Description: The driver detected a controller error on \Device\Scsi\ql2300x.

Data (words): offset 34 = 80120000 [ErrorCode: Link down error]

Event ID: 11

Source: ql2300

Description: The driver detected a controller error on \Device\Scsi\ql2300x.

Data (words): offset 34 = 80110000 [ErrorCode: Link up]
