Internal RDX docking stations and removable disk drives

Description

The internal RDX docking station is available as an internal device. 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. Figure 1 shows the front view of the internal RDX docking station cartridge.

Feature codes and part numbers

The internal RDX docking station includes a USB cable that is used to connect to an internal USB port. Table 1 provides the part numbers for the internal RDX docking station. Table 2 provides the part numbers of its supported disk drives.

Purchasing extra removable disk drives

For best results, use only the removable disk drives that are listed in Table 2.

The removable disk drives are a supply item that can be ordered as a feature code. To order in the United States and Canada, call 1-888-IBM-MEDIA. To order drives in other locations, contact your local provider of IBM® storage products.

IBM service representatives will not be dispatched to service or replace the removable disk drives.

Storing removable disk drives

Store removable disk drives in their protective containers, on a flat surface with the top side up. The storage area must be clean and dry, must have normal room temperature, and must be away from any magnetic fields. For best storage life, use the removable disk drives every six months.

Supported USB adapters and cables

The internal docking station must be connected to the internal, integrated USB port on the 9009-41A, 9009-41G, 9009-42A, 9009-42G, 9223-42H, or 9223-42S system.

Operating system or partition requirements

If you are installing a new feature, ensure that you have the software that is required to support the new feature and that you determine whether there are any prerequisites for this feature and attaching devices. For information about the prerequisites, see the Power Systems Prerequisite website.

Using the internal RDX 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.

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.

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.
