but is optional in the Sparc installlation. Currently, the software supports multipathing for fibre channel connections using supported host bus adapters. It does https://www.princeton.edu/~unix/Solaris/troubleshoot/mpathadm.html not currently support multipathing for parallel SCSI devices or IP over FC. For Sparc-based systems, multipathing support is enabled and disabled via the stmsboot -e and stmsboot -d commands. This command reboots the system to complete the process, so make sure that the right boot-device is included in the EEPROM settings before proceeding. When multipathing is enabled, copies of the /etc/vfstab and /kernel/drv/fp.conf files are unable to preserved to allow the changes to be backed out if necessary. For x86-based systems, directly edit the fp.conf to change the value of mpxio-disable to “no.” (Disabling it will involve changing it to “yes.”) After the change, run a reconfiguration reboot. 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. (Syntax guidance unable to get is included in the comments of the fp.conf file.) mpathadm Commands TaskCommand List available multipathing support mpathadm list mpath-support View properties for supported multipathing facilities. mpathadm show mpath-support facilityname List initiator ports. mpathadm list initiator-port Get initiator port properties. mpathadm show initiator-port portname List available logical units. mpathadm list lu Get logical unit properties. mpathadm show lu lunname List logical units associated with a target port. mpatadm list lu -t portname Configure auto-failback. mpathadm modify mpath-support -a off facilityname Disable a path. mpathadm disable path -i initportname -t tgtportname -l luname Adding Third Party Device Support Support for many third-party devices is not contained in the default version of the configuration file at /kernel/drv/scsi_vhci.conf.
