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 clustered-system configuration
and try again.
- If you still do not see
disks, reboot the machine by
issuing a reboot -- -rv command.
Note: You might see a "mode sense error" listed for each disk when you are running format for
the first time. This error is normal, and does not occur after the disks are 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#.
