The following considerations apply to the stmsboot -e, -d, and -u options:

■

You should reboot immediately after running the stmsboot command.

■

Ensure that eeprom(1m) boot device is set to boot from your current boot device. This is

required since the stmsboot command reboots the machine to complete the operation.

■

The stmsboot command saves a copy of your original /kernel/drv/fp.conf ,

/kernel/drv/mpt.conf and /etc/vfstab les before modifying them. See

Appendix C,

“Multipathing Troubleshooting,” if you encounter unexpected problems while using

stmsboot.

Note – The behavior of the stmsboot command in the Solaris 10 OS diers from the stmsboot

command provided by Sun StorEdge SAN Foundation software in the Solaris 8 and Solaris 9

OS. In the Solaris 8 and Solaris 9 OS, the stmsboot command is used to enable or disable

multipathing on the boot device only for SPARC based hosts only. In the Solaris 10 OS, the

command is used to enable or disable multipathing on all capable devices.

The stmsboot command is available on both SPARC and x86/x64-based systems from the

Solaris 10 Update 4 OS onwards. In the Solaris 10 Update 5 OS the stmsboot command is used

to enable, disable or update multipathing for Serial-Attached SCSI devices as well as FC devices.

To Enable Multipathing

Perform the following steps to enable multipathing on all multipath-capable devices on SPARC

or x86/x64 based systems. If you want to enable multipathing only on specic FC or SAS HBA

ports, refer to

“Enabling or Disabling Multipathing on a Per-Port Basis” on page 45.

The multipathing software automatically recognizes Sun supported devices. If you want to

enable multipathing on third-party devices, add entries to the /kernel/drv/scsi_vhci.conf

le as described by Device Name Change Considerations in

“Multipathing Considerations” on

page 42

Run the stmsboot -e command:

# stmsboot -e

WARNING: stmsboot operates on each supported multipath-capable controller

detected in a host. In your system, these controllers are

/devices/pci@780/pci@0/pci@8/SUNW,qlc@0/fp@0,0

/devices/pci@780/pci@0/pci@8/SUNW,qlc@0,1/fp@0,0

/devices/pci@7c0/pci@0/pci@1/pci@0,2/LSILogic,sas@1

/devices/pci@7c0/pci@0/pci@1/pci@0,2/LSILogic,sas@2

/devices/pci@7c0/pci@0/pci@9/LSILogic,sas@0
