A general system error occurred: No such device or address when consolidating disks

[tdubb123]

My vcenter server is having issues. IT would startup but then lose complete network connectivity. All vms on the same host and vlan are fine. Its just the vcenter vm.

IN the summary tab I see virtual machine disk consolidation is needed.

I shutdown the vm and tried to consolidate the disks but keep getting an error

A general system error occured: No such device or address

any idea?

Hello,

  do you have snapshots in this vm? If the vm is clean of snapshots try replacing de nic , also you may check forcing an active-pasive teaming (assuming that you have a teming active-active) in order of to be sure about the uplink used for all VMs is the same for this vCenter.

On the other hand, if is possible you can try to clone this vCenter server for merge disks, if the clone is not possible you can use Converter for this task.

Hope it helps you

it shows that there re no snapshots. however if I browse to the vm folder it sows a bunch of

vmdk and ctk files in the format

000001.vmdk

000002.vmdk

000003.vmdk

also

000001.ctk.cmdk

000002.ctk-vmdk

000003.ctk.vmdk

there are not snapshot files

I trie cloning the vmdk file with

vmkfstools -i /source/vmdk /destination/vmdk

but keep getting an error and timeout and killed at 11%

you have multiple snapshot, first at all, try to take a new snapshot and then "delete all" option.

If ths snapshots persist or is not possible to take new snapshots, check the snapshot chain following this KB:

Taking a new snapshot and then deleting all snapshots resolved the consolidation needs of the disks.
