Changing the Multipath Configuration
(iSCSI Connection for RHEL5, SLES9, or SLES10)
The procedure to change the multipath configuration varies depending on the type of OS that is used.
In this chapter, the multipath configuration of the following OSs is described:
• Red Hat Enterprise Linux 5 (Update 4 or later)
• SUSE Linux Enterprise Server 9 (Service Pack 3 or later)
• SUSE Linux Enterprise Server 10 (Service Pack 2 or later)
When using the following OSs, refer to "Chapter 9 Changing the Multipath Configuration (iSCSI Connection for
RHEL6, RHEL7, or SLES11)" (page 98) .
• Red Hat Enterprise Linux 6
• Red Hat Enterprise Linux 7
• SUSE Linux Enterprise Server 11 (Service Pack 1 or later)
The multipath configuration can be changed using the "mpdconfig" command. The "mpdconfig" command is
installed in the /opt/FJSVmpd/bin directory. Only a root-level user may execute the "mpdconfig" command.
This chapter describes how to change multipath configuration for iSCSI connection.
• When by-id names are not used, changing the multipath configuration may change the device names.
• Before starting an addition process, use the "iompadm info" command to check that the existing devices
are in normal status.
• Before starting a reduction process, check that the device not to be reduced is in normal status.
