Thank you very much.
Yes I can get downtime for cluster
You do not even need a downtime for the cluster, provided that your SAN disks allow for concurrent access (check with "lsvg <vgname>" if it is "enhanced concurrent capable" and if it is opened in concurrent mode).
If this is indeed the case:
- attach the new disks to both nodes, run "cfgmgr" on both nodes to create the new devices. Check with "lspv".
- add the new volumes to your VGs on the active node:
- mirror the old disks to the new disks. Switch off automatic sync and do a "syncvg" afterwards, it is usually much faster. Use the "-P" switch to let it run in parallel:
- after the syncing is finished do a "learning import" on the passive node. The passive node knows only the old disk to be in the VG so far, so use this to reimport the VG definition from:
- on the active node unmirror the VG, removing the mirror on the old disk, then move that old disk out of the VG:
- again do a "learning import" on the passive node to sync the VG definition across cluster nodes, this time from the new disk:
Remove the zones from the fabric and delete the old hdisk-devices. When running "cfgmgr" again they should not be discovered any more.
hi! i got a rhel 6.3 host that already have an xfs filesystem mounted from a SAN (let's call it SAN-1) whose size is 9TB.
i will be receiving another SAN (let's call it SAN-2) storage of 15TB size. this new addition is physically on another SAN storage. SAN-1 is on a Pillar storage while the new... (6 Replies)

I'm New to AIX / VIOS
We're doing a FC switch cutover on an ibm device, connected via SAN.
How do I tell if one path to my remote disk is lost? (aix lvm)
How do I tell when my link is down on my HBA port?
Appreciate your help, very much! (4 Replies)
I have an IBM blade running RHEL 5.4 server, connected to two Hitachi SANs using common fibre cards & Brocade switches. It has two volume groups made from old SAN LUNs. The old SAN needs to be retired so we allocated LUNs from the new SAN, discovered the LUNs as multipath disks (4 paths) and grew... (4 Replies)
Hi,
I am very new to HP-UX, and we're going to be doing a SAN migration.
We're going to take down the machine, and zone it to the new SAN.
My question is, will the device names change and will that interfere with the LVM?
If the new disks come in with different device names, how would I... (3 Replies)
I am going to do a SAN Array migration and need the sequence of steps required on the Solaris cluster before moving the old array luns to new array luns.

Hello gurus,
I am a SAN Admin - not very familiar with the HPUX administration - so need help with the steps in regards to the migration I need to do at my client place.
Environment: Migrating from CX4 to VMAX - using OR/Hot Pull.
Here are the steps I have put together - HPUX gurus please... (5 Replies)
Has anyone tried SAN to SAN mirroring on IBM DS SAN Storage.
DS5020 mentions Enhanced Remote Mirror to multi-LUN applications
I wonder if Oracle High availibility can be setup using Remote Mirror option of SAN ? (1 Reply)
Hi everyone,
I wonder if I can canvas any opinions or thoughts (good or bad) on SAN attaching a SUN V880/490 to an EMC Clarion SAN?
At the moment the 880 is using 12 internal FC-AL disks as a db server and seems to be doing a pretty good job. It is not I/O, CPU or Memory constrained and the... (2 Replies)
Hi, I'm going to be involved in a migration of SAN islands to one big SAN. I've not worked with SANs before and I'm not sure how to approach this. I suspect the disk devices on the HP servers are going to change, when the EVA's and servers are plugged into this new Cisco 9509 switch.
