How To Check Multipathing In Solaris 10
The Multipath Daemon If you find you have trouble implementing a multipath configuration, you should ensure the multipath daemon is running as described in "Setting up DM-Multipath".

Occasionally, the path state and the dm state of a device will temporarily not agree. For example, the following command sequence displays the multipath configuration, including the defaults, before exiting the console.
For Sparc-based systems, multipathing support is enabled and disabled via the stmsboot -e and stmsboot -d commands. You may check 'prtconf -v' andsee the device is ina normal state. To enable or disable multipathing on a per-port basis, the mpxio-disable parameter may be set on a port-specific line in the fp.conf.

The multipathing support libmpscsi_vhci.so supports T10 target port group compliant devices by default. Currently, the software supports multipathing for fibre channel connections using supported host bus adapters. Note - This operation is not allowed when the given path is the last operational path remaining. http://osdir.com/ml/os.solaris.opensolaris.storage.general/2007-01/msg00009.html When Auto-Failback is enabled, the initial path comes back online, failover to the initial path automatically occurs. 1.

Solaris 11 Multipathing
The terms used in this chapter to denote a path, initiator port, target port, and logical unit are consistent with the T10 specification. https://www.princeton.edu/~unix/Solaris/troubleshoot/mpathadm.html If, however, you are using a multipathed device for which the features "1 queue_if_no_path" option is set as a compiled in default, as it is for many SAN devices, you must Error Unable To Get Mpath-support List Run the mpathadm disable path -i initiator-port-name -t target-port-name -l logical-unit-name command. # mpathadm disable path -i 2000000173018713 -t 20030003ba27d095 -l /dev/rdsk/c4t60003BA27D2120004204AC2B000DAB00d0s2 Note - The disabled state is not persistent across Mpathadm: Error: Unable To Get Configuration Information.

This will rebuild the initial ramdisk and afford multipath the opportunity to build it's paths before the root file system is mounted by UUID. The 4 configuration files used in case of Solaris 11 are the same, performing the same task. By default the auto-failback is enabled. Select an initiator port and a target port name. 5.
