SUMMARY: Increase the partition size of Veritas Encapsulated Disk

Many thanks to Darren Dunham whose expertise helped me resolve this issue. 

	The Problem: 

	I have a 9 GB Root Disk (veritas encapsulated) with following partitions 
	running on Solaris 8 as below: 

	Part      Tag    Flag     Cylinders        Size            Blocks 

	  0       root    wm       0 -  285      501.48MB    (286/0/0)   1027026 

	  1       swap    wu     286 - 1454        2.00GB    (1169/0/0)  4197879 

	  2     backup    wm       0 - 4923        8.43GB    (4924/0/0) 17682084 

	  3        var    wm    1455 - 1740      501.48MB    (286/0/0)   1027026 

	  4 unassigned    wm    1741 - 3506        3.02GB    (1766/0/0)  6341706 

	  5        usr    wm    3507 - 4091        1.00GB    (585/0/0)   2100735 

	  6          -    wu       0 - 4923        8.43GB    (4924/0/0) 17682084 

	  7          -    wu    4923 - 4923        1.75MB    (1/0/0)        3591 



	Now I want to increase the partition size of /var file system. if I use 
	18 GB Disk and do ufsdump/ufsrestore I first need to create a partition 
	and then do ufsdump/ufsrestore. Now I need to know how do I dump slice 6 
	and 7 which is created by Veritas Voulme Manager and how partition 6 
	will reflect that as 18 GB (entire disk)? Also what about slice 7? Just 
	create a 2 MB partition for that? 

	If I use dd to create an image on 18 GB disk (from 9 GB Root disk) is 
	there a way I can increase the partition? 

	Any Help/Suggestion/Pointer will be greatly appreciated. 

	I will summarize. 



	The Solution: 



	 1) Attach 18G Disk 

	 2) Create partition 

	 3) ufsdump/restore partitions - /, /usr, /opt, /var 

	3.1  On the new disk, reset /etc/vfstab and /etc/system to boot from  that disk 
	3.2  Disable VxVM on that disk 

	     (touch /mnt/etc/vx/reconfig.d/state.d/install-db)  When that  machine boots, it'll have VxVM binaries, but won't import any disk      groups. 

	3.3  Boot from new disk.  Verify everything works. 



	 4) encapsulate new root disk 



	This step means that you run 'vxinstall' to install/encapsulate the new 
	disk.  This creates a new rootdg and re-enables VxVM. 



	 5) import all DGs. 



	During the vxinstall step you're asked what to do with the other disks 
	in the system (initialize, encapsulate, etc...).  you should 

	*ignore* all the disks other than the root disk. 



	After you get the encapsulated disk booted, then just vxdg import the 
	other diskgroup and mount up the volumes.
	
	

	If there's ever a problem, you haven't touched your first rootdisk.  You 
	can always go back to it and reboot.
