From May 27th onwards we are unable to take the backups using Data protector.

I have executed rescaning of hpscan -a utility but haven't worked.

Kindly help me to solve this.


Thank you.

Hi,

When we start the backup or scaning using this server drive. The following error is reported.

hi,

in this case i would check the zoning / physical conection and of course library and switch status

- if its possible to reboot the server, do it.
