Many thanks eeg3,
if i want to preserve data on volume then i have to follow these steps.plz correct me if i m wrong.
- Unregister all objects from the datastore including VMs and Templates
- Ensure that no 3rd party tools are accessing the datastore
- Ensure that no vSphere features, such as Storage I/O Control, are using the device
- Mask the LUN from the ESX host by creating new rules in the PSA (Pluggable Storage Architecture)
- Physically unpresent the LUN from the ESX host using the appropriate array tools
- Rescan the SAN
- Clean up the rules created earlier to mask the LUN
- Unclaim any paths left over after the LUN has been removed
regards
Mr VMware
