Hello,
I have some doubts about the dvd/cd physical on power machine and AIX.
I see on my AIX lpar and see there is 1 DVD drive and its physical location
Code:
bash-4.4# lsdev | grep cd0
cd0 Available 03-00-00 SATA DVD-RAM Drive
bash-4.4# lscfg -vpl cd0
cd0 U78CB.001.WZS0GY4-P2-D15 SATA DVD-RAM Drive
Manufacturer................IBM.
Machine Type and Model......RMBO0140532
ROS Level and ID............RA64
Device Specific.(Z0)........058002028F000030
Part Number.................00RW610
EC Level....................N99020
FRU Number..................00RW611
Hardware Location Code......U78CB.001.WZS0GY4-P2-D15
PLATFORM SPECIFIC
Name: disk
Node: disk
Device Type: block
I check on the managed system IO tab. See the screenshot.
I didn't find the location code of DVD drive above in the list (screenshot attached)
Code:
U78CB.001.WZS0GY4-P2-D15
I'm surprised that on power machine did not have any optical device. Please correct if I'm wrong for this case.
Try to mount the DVD to see its content but not success. But the status of DVD drive is available, it should mean that DVD media is loaded. I'm not sure.
Code:
bash-4.4# mount -v cdrfs -o ro /dev/cd0 /cd
mount: 0506-324 Cannot mount /dev/cd0 on /cd: The device is not ready for operation.
After upgrading to solaris 10 (from sol 8) on a SUN Blade 1500, it seems that the dvd/cd-rom does not accept dvds nor cds in the dvd drive.
After I insert a dvd/cd in the drive, the disk is simply ejected (!)
Is it possible that the upgrade made the system not being able to recognize these... (2 Replies)
I would like to check for the existance of media in a DVD drive prior to running a mkcd. Is this possible? I have accomplished this in the past with tctl, but that was with a tape drive. Any help is appreciated.

Hi there

Hello,
It's some tool in AIX to check what kind of media (DVD+RW DVD-RW DVD-RAM) is inserted in drive?
In linux there is very nice tool called dvd+rw-mediainfo. (0 Replies)
I was having problems with the DVD-ROM drive not being recognized. I thought it was a configuration issue, but it appears to be a hardware problem. Now the system hangs at boot. This last time I tried it, it said:
At which point, it hangs. (1 Reply)
Currently have an issue were we use a script to load a security .dat key. The script was failing to load stating "Unable to open directory". I ssh'd into the server and performed an ls -la on the /cdrom directory. I show the usual cdrom0 but the directory on the cd should be key but is showing... (0 Replies)

Hi Guys,
I think i probably know the answer to this question, but ill put it out there.
I have access to one, and only one SunFire v240 with no DVD drive. I have been tasked with installing Solaris 10 on there (Solaris 8 is on at the moment).
The obvious thing was to try a USB DVD... (4 Replies)

mknod
MKNOD(8) BSD System Manager's Manual MKNOD(8)NAME
mknod -- build special file
SYNOPSIS
mknod name
mknod name [b | c] major minor [owner:group]
DESCRIPTION
The mknod utility is deprecated on modern FreeBSD systems.
The mknod utility creates device special files. To make nodes manually, the arguments are:
name Device name, for example /dev/da0 for a SCSI disk or /dev/pts/0 for pseudo-terminals.
b | c Type of device. If the device is a block type device such as a tape or disk drive which needs both cooked and raw special files, the
type is b. All other devices are character type devices, such as terminal and pseudo devices, and are type c.
major The major device number is an integer number which tells the kernel which device driver entry point to use.
minor The minor device number tells the kernel which subunit the node corresponds to on the device; for example, a subunit may be a file
system partition or a tty line.
owner:group
The owner group operand pair is optional, however, if one is specified, they both must be specified. The owner may be either a
numeric user ID or a user name. If a user name is also a numeric user ID, the operand is used as a user name. The group may be
either a numeric group ID or a group name. Similar to the user name, if a group name is also a numeric group ID, the operand is used
as a group name.
Major and minor device numbers can be given in any format acceptable to strtoul(3), so that a leading '0x' indicates a hexadecimal number,
and a leading '0' will cause the number to be interpreted as octal.
The mknod utility can be used to recreate deleted device nodes under a devfs(5) mount point by invoking it with only a filename as an argu-
ment. Example:
mknod /dev/cd0
where /dev/cd0 is the name of the deleted device node.
COMPATIBILITY
The chown(8)-like functionality is specific to FreeBSD.
As of FreeBSD 4.0, block devices were deprecated in favour of character devices. As of FreeBSD 5.0, device nodes are managed by the device
file system devfs(5), making the mknod utility superfluous. As of FreeBSD 6.0 device nodes may be created in regular file systems but such
nodes cannot be used to access devices.
SEE ALSO mkfifo(1), mknod(2), devfs(5), chown(8)HISTORY
A mknod utility appeared in Version 6 AT&T UNIX.
