Using the external RDX removable disk drive for backup and restore
The external RDX removable 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
the mksysb process is complete, the removable disk drive can be used to boot the system. If you mount
the removable disk drive, you can display and copy files to and from the UDF file system on the removable
disk drive.
The AIX commands, tar, backup, restore, dd, and cpio can write to the removable disk drive as a raw
device or non-raw device. You might get improved performance by using the device as a raw device.
See the AIX documentation for additional information.
Using the disk drive with the IBM i operating system
The IBM i operating system configures the drive as a removable media drive with a name in the format
RMSxx, for example, RMS01.
The drive and cartridge are used with optical commands and utilities (for example, WRKOPTVOL and
INZOPT), and reports media in the Optical File System (QOPT).
See the IBM i operating system documentation for information about using the IBM i commands: copy
and backup.
Using the disk drive with the Linux operating system
The Linux operating system configures the drive as a disk drive with a name in the format sdx, for
example, sda, sdb, and sdc.
See the Linux documentation for information about using the Linux commands: copy and backup.
