If you are using the subsystem device
driver (SDD) for multipathing support on an
Oracle SPARC host, you must use these instructions to configure the LUNs.
The following instructions are based on the Oracle OS 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 " that is 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#.
