Re: [Veritas-vx] recovering lost vxvm private data from vxprint -hvt and vxprint -htg outputs
Hi Arjun, Is there any reason why you cannot encapsulate the root disk one more time?? What caused the problem?? Essentially the reason you need to encapsulate the root disk is to mirror it. Re-encapsulate, reboot and mirror should work. The technote for recovering DG's is http://entkb.symantec.com/security/output/a180321.html But your is a rootdg, I have never recovered a rootdg using the procedure.

Re: [Veritas-vx] Disconnecting HBA
I would remove the access via access logix (use navicli/navisphere) for one of the paths say SPA2 (500601621060162C) or SPB2 (5006016A1060162C). All paths would be failed to only one SP i.e. one HBA on the host. (I assume you are using Solaris) Then unconfigure that HBA via "cfgadm" and remove the dead paths via "devfsadm" or "luxadm", if required. If you are using powerpath, then remove paths from it as well via "powermt/powercf". Then connect/zone/configure that HBA to the different CLARiiON and/or SAN fabric. -Khurram VC123 <[EMAIL PROTECTED]> wrote: Note: forwarded message attached. Building a website is a piece of cake.

It's not so much that you can retrieve the private data as using the vxprint may allow you to create new VxVM objects in the exact location as the old objects. If this is done, all the data should be there. This is a bit trickier with encapsulated disks. Was there something in rootdg other than the OS? Usually I use rootdg only for the OS, allowing me to simply recreate it without worring about losing data. -- Darren Dunham [EMAIL PROTECTED] Senior Technical Consultant TAOShttp://www.taos.com/ Got some Dr Pepper?

Re: [Veritas-vx] recovering lost vxvm private data from vxprint -hvtand vxprint -htg outputs
You can't recover the private area directly, but if you rebuild logical volumes that are on the exact same boundaries, the file systems inside there will still be intact (presuming nothing wrote to those areas of the disk during the disaster). Probably the best instructions on doing something like this is the rebuilding of EMC BCV volumes so that they get a new disk group ID -- searching on "Veritas" and "BCV" should find the procedures. They usually depend on a specific format of "vxprint" having been saved beforehand so you may have to adjust the procedures to fit what data you have. Essentially it'll be a series of "vxmake" commands specifying the device, offset and lengths of the originals from the saved output for the subdisks, then building those into plexed and finally volumes. Best of luck!
