IBM Power Systems RDX Manual page 94

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.
Using the emergency eject function
To normally eject a removable disk drive, press the eject button, wait for the eject button to stop flashing
green and for the removable disk drive to be ejected. If a drive is stuck and does not eject, the drive and
the dock need service. Complete the following steps to eject the cartridge:
1. Prepare the system for servicing by following the instructions at: "Preparing the system to remove and
replace an internal RDX docking station in the 9009-41A, 9009-42A, or 9223-42H" on page 29 (http://
www.ibm.com/support/knowledgecenter/POWER9/p9ia1/p9ia1_914_924_prereq.htm).
2. Insert a large straightened paper clip (or similar object) into the emergency eject hole.
Note: Do not insert the object in the hole at an angle. Keep the object straight and apply some force to
eject the drive.
3. When the drive has been ejected by the docking station, grasp the exposed sides of the drive and pull
the drive straight out.
4. Prepare the system for operation by following the instructions at: "Preparing the system for operation
after removing and replacing an internal RDX docking station in the 9009-41A, 9009-42A, or
9223-42H" on page 48 (http://www.ibm.com/support/knowledgecenter/POWER9/p9ia1/
p9ia1_914_924_postreq.htm).

station.
Power indicator
The eject button is illuminated by a power indicator light. The following table describes the operation of
the power indicator.
