Configuring SLES for a FibreCAT S80

This document (3870694) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 10
SUSE Linux Enterprise Server 9
 

Situation

Fujitsu Siemens Computers FibreCAT S80 fibrechannel SAN device

Basically, with DM MPIO, everything should function when activating these services on SuSE Linux Enterprise. However, these services rely on scsi_id for calculation of a unique device id for each scsi device provided by the SAN. On SLES, scsi_id will not correctly report unique IDs for the FibreCAT S80 with the default configuration.

Resolution

Creating a customized /etc/multipath.conf file will solve this problem. This file should contain:

getuid_callout "/sbin/scsi_id -g -u -p 0x80 -s /block/%n"
 

Additional Information

The default, built-in, call in the multipath tools is:

getuid_callout "/sbin/scsi_id -g -u -s /block/%n"

so, the only difference is the creation of the file and specifying the '-p 0x80'.
