So we just installed a new set of drives from Dell to increase our total storage.

After doing so the PV is no longer able to be found by the MDSM.

The PV is now out of warranty.

Is there a reset procedure or something that I should follow?

I want to set this up as a new PV so would like to wipe all settings and get it working again.

I do have the password reset cable and can get into the PV that way. 

TIA
