Hi Guys,

then

   #

  echo "\nPDMPROD CLONE (EU) are already mounted+shared! Please, do not run this script now!\n"
  exit 0
fi

Looks like can not mount /pdmprod_u05 and /pdmprod_u07

How to solve this error, sorry to say but I have no idea as how to go about this.

Please guide me.

Thanks.

You need to start with your SAN admin and confirm the disk is still present and visible. It looks like your server isn't seeing it for some reason.

Wow ! Wonderful that means/ look like someone from storage team has something to do to clear this error and not me as OS admin.

right ?

Thanks
