Supported operating systems

USB Removable Disk Drive is supported on the following versions of the AIX and

Linux

operating systems:

v AIX 5L Version 5.3 with the 5300-11 Technology Level, or later

v AIX Version 6.1 with the 6100-04 Technology Level, or later

v Red Hat Enterprise Linux version 3 Update 7, or later

v SUSE Linux Enterprise Server 10, or later

Using the USB Removable Disk Drive for backup and restore

The disk drive is a backup 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 drive with AIX

AIX names the drive usbmsx. For example, usbms1 and usbms2. AIX also can use

the device as a raw device. For example, rusbms1 and rusbms2.

AIX uses the removable disk drive differently depending on the program being

used. The AIX mksysb command builds a list of files to back up, 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 tar, backup, restore, dd, and cpio commands 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 drive with Linux

Linux 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 Linux copy and backup

commands.

Setting the write-protect switch

The removable disk drives have a red, write-protect tab that is located on the back

of the drive. To write-protect a drive, slide the write-protect tab toward the lock

symbol. To disengage write protection, slide the tab to the unlock symbol.
