Using the USB Removable Disk Drive for backup and restore
The disk drive is a back up and restore device that can be used as an alternative to tape drives. The
removable disk drive is not a replacement for regular disk drives and cannot be used as part of a disk
array.
Note: If power is lost during a backup to the disk, the data can be compromised. Verify the data or rerun
the backup.
Using the disk drive with the AIX operating system
The AIX operating system names the drives as drive usbmsx, for example, usbms1, and usbms2. The AIX
operating system can also use the device as a raw device, for example, rusbms1 and rusbms2.
The AIX operating system uses the removable disk drive differently depending on the program that is
being used. The AIX command mksysb, builds a list of files to backup, creates a universal disk format
(UDF) file system, and puts a boot image and the root volume group on the removable disk drive. When
