Troubleshooting

Problems and Solutions

Problem 1

Error Message ID: 51 in event viewer when attempting to install

 

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

 

array storage group. The text of the message is:

 

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 Primus case 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 Primus case 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]
