Where in the datastore is my VMDK? (extends)

[mrbrown66]

Hi guys,

I have a 1TGB VMFS3.21 Datastore split up into 3 x 350GB LUNs extended.

Is there anyway of determining which one of these extends a VMDK resides in ?

I recently had an outage for a handful of virtual machines reporting "No Guest OS", upon powering them off and on again everything was fine. Windows gives the ever helpful error message "Previous shutdown was unexpected"

I suspect a storage issue with one of the LUNs but I am not sure how to confirm this. Bonus points to the first person with the right answer !

Thanks

MrB

p.s I have discovered extending is probably not the best idea, so will be working towards individual datastores rather than extends.

Short answer - I don't think/know of anyway to find this out without speaking to VMware Support...

Probably its not the best way but you could launch a disk benchmark on the virtual machine and then check, using you SAN performance monitor (if you have one), which lun is doing a lot of traffic, that lun will be the extend in which your vmdk reside.
