Migrated VM to new datstore now virtual drives are missing or unable to be browsed

A virtual machine was migrated to a new datastore and now the drives are unavailable.  When connected into the virutal machine and you access disk management (machine is a 2003 SQL server) the drives required to be initialized.  After drives were initialized assigned a drive letter, drive is unable to be browsed.  I had something like this occur months back and it ended up requiring a rebuild.  Hopefully I can avoid that and would like to try and identify why this is happening.

How was the virtual machine migrated?

This suggests the disks have been wiped, or new disks have been created.

browsed the datastore and I can identify all the appropiate vmdk's the sizes look accurate
I am now going through the log to identify any potential errors

Is all your hardware certified for use with VMware vSphere?

What type of storage?

iSCSI, FC, NFS?

Can you move a test machine and reproduce the fault?

hardware is definitely certified (this network supports around 500 navy and contractors)
Storage is netapp -- fiber channel
I have had this issue happen one other time approximately 3 months ago

It would seem that (just looking over my notes) if you have multiple drives attached to a VM that span 2 datastores and then migrate that vm to a new datastore this debacle occurs
  Atleast that is what happened for me it seems

I would seriously escalate this into VMware Support and NetApp Support, there appears to be some serious issue with your storage for corruption within the VMDK to be occuring with this equipment.

I was afraid you say that as the netapp is definitely the one thing I know little of since I always managed vmware with EMCs.  I also know that upon initial configuration the netapp tech did not complete all his tasks in the days alotted upon purchase, install, and configuration.  Time to hassle netapp support I guess.  Thanks you

I've never seen this issue with any storage, HP, EMC, NetApp, Dell etc

If it can be easily reproduced, it will be easy to home in on the issue.

I am in the process now of creating a VM associating virtual disks across multiple datastore and seeing if I experience this problem.  That was the first thing I was able to identify in my notes (I maintain a journal since im the vmware admin, DBA, Exchange can be troublesome keeping track) from when I experienced this problem roughly 3 months ago.  I am not wrong though assuming in theory it is fine (maybe not best practice) to have virtual disks from more then one datastore associated with a VM in a HA/DRS configuration

Completely normal to have virtual machine disks, across different datastores.

you may have different SANs, SSD LUNs, for DB and Logs, but OS LUNs on SATA etc
