When SnapManager backup fails

When a SnapManager backup failed I …
– manually ran the SQL job – which failed again
– remoted onto the server and read the logs (start/ NetApp/ SnapManager for SQL Management) – there weren’t any for that day!
– fired up SnapDrive (start/ NetApp/ SnapDrive) and examined the Disks – there weren’t any (dum dum duuuum)
– restarted all Snap~ services (x3)
– found the disks had re-appeared in Snapdrive
– manually started the sql backup job – success!
