27.10.1 Recognising a broken disk
If, after logging onto ArchivistaVM, you look under options, in the square brackets you should only see [UU] for two hard disks, [UUUU] for four or correspondingly more 'U's in the case of several hard disks. If, as on the following screen, you see a [U_], a [_U], or [UUU_] in the case of four disks, this means that a hard disk is defective and must be replaced.
: Don't worry. With good backups, this is not as serious as you might think. If you have not created any backups, it is advisable to do that first.
