*Title: UFS LUN Expansion This is the procedure I used to grow a UFS Solaris Volume Manager (SVM) with EMC Powerpath after a Clariion LUN expansion. #. Unmount the filesystem. #. type ''format -d __'' where __ is the name of the emcpower device #. once in format, type ''p'' followed by ''p'' to show the current partition table. _Make a copy of the partition table as it will be overwritten!_ #. type ''q'' and then ''type'' #. Next, pick option ''0 autoconfigure''. _Warning: This will overwrite your current partition table._ #. type ''p'' to display and modify the new partition table. After you make any necessary modifications to disk slices, type ''l'', then ''q'' #. ''growfs /dev/rdsk/__'' where __ is the name of the emcpower device #. Mount the filesystem. *Troubleshooting If the filesystem is not resized, check the format output again. Make sure slice 2 is equal to the size of the LUN expansion. If the disk size is not updated, then try ''cfgadm -al'', ''devfsadm -C'' or ''reboot -- -r''. Older fiber cards require a reboot in order to recognize the disk expansion.
