If you are using the subsystem
device driver (SDD) for
multipathing support on a Sun SPARC host, you must use these instructions
to configure the LUNs.
The following instructions are based on the SunOS 5.8 Generic_108528–16
version. Use a bash shell as root to correctly configure your path.
You
can use the following steps for all HBAs that are used with SDD:
- Delete the following files:
- /etc/vpathsave.cfg
- /etc/vpath.cfg
- Use the format command to check for disks.
- If you see disks, proceed to the next step.
- If you do not see disks, verify the configuration of
your HBAs and clustering configuration and try again.
- If you still do not see disks, reboot the machine by
issuing a reboot -- -rv command.
Note: You may see a "mode sense error" listed for each
disk when running format for the first time. This is normal, and will
not occur once the disks have been labeled.
- Configure SDD by issuing the cfgvpath -c command.
- Issue the devfsadm -C -v command to scan
for disks.
- After the devfsadm command completes, issue the vpathmkdev command
to create vpaths for the new disks.
- Issue the format command and browse the
returned list for your vpaths.
- The devices are now accessible from /dev/dsk/vpath#.
