USB Blu-ray drive read-only support

AIX® Version 6.1 with the 6100-06 Technology Level, and later, recognizes and configures USB attached Blu-ray drives.

This feature is included in the following device package:

The capability of the AIX operating system to read Blu-ray media is validated against a sample of industry standard original equipment manufacturer (OEM) USB Blu-ray drives.

USB Blu-ray drives are configured by using 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 International Organization for Standardization (ISO) file system (read-only ISO 9660), the Universal Disk Format (UDF) file system (Version 2.01, or earlier), and standard optical media access commands, such as dd and tar.

The AIX operating system 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 that are encountered during the write operation.

The AIX operating system 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 the USB port of the system 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 cdn

When a drive is in the available state, you can reconnect it to the system. 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.
