Migration storage and cluster
Hi all,
We are migrating data to DMX-1000 from an DMX-3000.I have one cluster with 2 nodes edes220 and edes221.
So, I basically need migration all dates and the cluster to DMX-1000 from DMX-3000, this steps is correct ?

Re: Migration storage and cluster
Hello,
maybe a few more information here would be helpful.
Do you boot HPUX from the Symmetrix box ? Or is your vg00 on internal disks of the servers ?
If you only have data on the Symmetrix, then the easiest way to migrate them is through LVM mirroring. Simply add identical physical volumes from DMX 1000 into your data volume groups and lvextend your current logical volumes onto these disks. You need MirrorDisk/UX software in order to accomplish this. What is your HPUX version and what OE are you using ?
