How To:Using removable hard disk changers as Virtual tapes

New feature in amanda-3.3

Amanda can easily use removable hard disk as virtual tapes, the user only needs to mount/umount the hard disk.

 autolabel "AMANDA-%%%" any
 meta-autolabel "META-%%%"
 define changer removable-disk {
    tpchanger "chg-disk:/amanda/diskchanger"
    property "NUM-SLOT" "4"
    property "AUTO-CREATE-SLOT" "yes"
    property "REMOVABLE" "yes"
 }
 tpchanger "removable-disk"

• Four slots (NUM-SLOT) is automatically created (AUTO-CREATE-SLOT) on each mounted disk.
• Each slot (autolabel) is labelled with a distinct label.
• The REMOVABLE property check that something is mounted.
• Each hard disk get a meta label. In the future, amanda will be able to ask to mount the disk with the meta label when it require a specific label.

Assigning meta label to already labelled volumes

If you already use removable hard disk, these disk don't have a meta label, you can easily assign a meta label to each label with the amlabel command

 amlabel <conf> <label> --meta <meta-label> --assign

You must assign the same meta label to all label on the same removable hard disk.
