We've been having issues with our HP MSA 2312sawith seeing parity errors plus the enclosure being in a degraded status. I've contacted HP and after updating the firmware on the controllers and hard drives after a verify disk process fails again they want me to run a verify vdisk VHD1 fix yes from the CLI.y understanding is this command will go through and fix the parity issues. HP recommends backing up everything on the MSA before running this command. If this command just fixes parity is backing up the 1.5 tb worth of VHD's on the MSA necessary before running this process? Additionally HP informed us we needed to stop all I/O to the MSA prior to and during this process. This involves stopping all virtual hyper v guests and hosts and shutting them down. Is this required or just recommended? I tried to get a estimated tome frame for scheduling downtime but HP wasnt much help. The regular verify took about 5 hours befogging retiring out. How long would the fix yes option take? The VDisk is about 1.5 tb with total space on the MSA being about 1.8 tb.
