Flash copy from IBM storage - with ESXi 5.0

Jump to solution

     Hello

I would really searching a answer for my questions for the flash copy using Vmware enviorment, can anyone answer my questions?

we have two enviorment prod and DR enviroment

we have assigned 200 gb lun to production and we formwated as vmfs and then allocated to VM's as vmdk file ( around 5 volumes including C drive)

Now we have Flash copy made available on DR environment, now my question is.

if we do rescan on DR environment with after enabling re-signature, does VMware will still recognizing as VMFS volume?? of 200 GB flash copy lun and can we get all VM's in that datastore? - any issue from the duplicate volume identify prospective from IBM storage?

I have same questions like below discussion but that discussion not answered hence questioning again in new discussion

Yes, VMware will retain any data on volume and mount it... the datastore may will get a new label as snap-<snapID>-<oldLabel> and you can rename the datastore later or before mount the datastore copy, set the Advanced Parameters LVM.EnableResignature to 1 on ESXi hosts.

After mount the datastore you can browse the datastore and register the VMs... and about the IBM storage perspective, the source and target volume from Flash Copy have different IDs.

Hello,

I would appreciate any help with documents and guidelines on how to recover
flash memory VMware ESXi 5.0 and above server running in the Mother-board on IBM x-series servers.

Haven looked up some documents, I noticed that there are recovery CDs up to  ESXi 4.1
but no information on how or what tools to use for the recovery of versions above 4.1.

Please point me to documents describing the procedure.

Thank you.
