VMWare unrecoverable disk corruption...

You have a SQL Server VM (VMWare) that has had an unrecoverable disk corruption. It has 250gb of databases on it. The c-drive is the drive that has the corruption. You don't know where the data is for the DBs.

What resources would you have to engage?
What would your steps be to resolve?
How long would it take for you to have a server back online?

Any ideas?

is the VMDK file still accessible using VMware Virtual Disk Manager?
LobsterguyAuthor Commented:
I forgot to put the following. I'm just the DBA. So engineering handles the VMs and storage handles the storage.

I'd assume I'd need to check that the VMDK file is still accessible. If so then what?
bbaoIT ConsultantCommented:
if the VMDK file is accessible that means that's single file issue (database file) rather than a disk issue (worse, as multiple files maight be affected)

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

The OS won't boot anymore. Still a DB issue?

> The OS won't boot anymore. Still a DB issue?

apparently, no.

if "corruption" here just means the guest OS is no longer bootable, your DB files might be still in good condition. simply run VMware Virtual Disk Manager to open the VMDK file and copy the DB files to somewhere safe.
LobsterguyAuthor Commented:
But how would I get the OS to function again? Is there something that can be done with the VMDK files to repair the corruption? Or would I be looking at building a new VM?
bbaoIT ConsultantCommented:
i would first make a copy of the corrupt VMDK file and keep it intact and safe.

secondly i would get the DB files from the corrupt VMDK file and try restoring them from another known-good SQL server.

lastly, troubleshoot against the corrupt VMDK file and see if the virtual disk could be bootable and the OS could run in safe mode etc...
