Question
Can I use a Blu-Ray media drive in AIX?
Answer
USB Blu-ray drive read-only support
AIX Version 6.1 with the 6100-06 Technology Level recognizes and configures USB attached Blu-ray drives. This feature is included in the following device package:
devices.usbif.08025002.rte USB Mass Storage Device Software
The capability of the AIX operating system to read Blu-ray media is validated against a sample of industry standard OEM USB Blu-ray drives.
Note: The AIX USB host-controller device driver supports USB 2.0 on AIX Version 5.3 with Technology Level 5300-10 and later and AIX Version 6.1 with Technology Level 6100-03 and later. The USB 2.0 based Blu-ray devices are supported.
USB Blu-ray drives are configured with logical names, such as cd0 and cd1. The drives present both raw and block special files. For example, the raw special file for cd0 is /dev/rcd0, and the block special file is /dev/cd0.
The read-only capability is provided for the ISO file system (read-only ISO9660), the Universal Disk Format (UDF) file system (version 2.01, or earlier) and standard optical media access commands, such as dd and tar.
AIX does not support the write operation to CD, DVD, or Blu-ray media present in the USB Blu-ray drive. Although the write operation is not prevented (if the drive is write capable), IBM does not provide support for any issues encountered during the write operation.
AIX does not support plug-and-play for USB Blu-ray drives. To make a USB Blu-ray drive available to AIX users, a root user must connect the drive to a system's USB port and run the following command:
- # cfgmgr -l usb0
After the drive is removed, the drive remains in the available state in the Object Data Manager (ODM) database until the root user runs the following command:
- # rmdev -l cd<n>
When a drive is in the available state, you can reconnect it to the system, and it can be remounted or reopened. If a drive is disconnected from a system USB port while it is still open to a user, you cannot use that drive until you close and reopen it.
