12. Once you have done this to all switches in the fabric and verified that it has
re-converged properly, issue the command cfgEnable [effective zone
configuration] on one of the switches in that fabric. For example:
cfgEnable my_zones
13. Clean the lvmtab file by using the command vgscan.
14. Change to /dev and untar the file that was tared in step 4. For example:
tar –xf /tmp/jbod.tar
15. Import the volume groups using vgimport. The proper usage would be
vgimport –m <map file> <path to volume group> <physical volume path>.
For example:
vgimport –m /tmp/jbod_map /dev/jbod /dev/dsk/c64t8d0
/dev/dsk/c64t9d0
16. Activate the volume groups using vgchange. The proper usage would be
vgchange –a y <path to the volume group>. For example:
vgexport –a y /dev/jbod
17. If you are not using multi-pathing software, mount all devices again and
restart I/O. For example, mount /mnt/jbod
18. If you are using multi-pathing software, re-enable the affected path. The
preceding steps do not “clean up” the results from ioscan. When viewing the
output of ioscan, notice the that the original entry is still there, but now has a
status of NO_HW.

19. To remove the original (outdated) entry, use the command rmsf (remove
special file). For example:
rmsf –a –v /dev/dsk/c65t8d0
# ioscan -funC disk
