Removing the CD ROM from DLPAR and assigning it to another LPAR

On the LPAR find out where the CD-ROM is assigned:

# lsdev -Cc cdrom
cd0 Available 03-08-00 SATA DVD-ROM Drive

# lsdev -Cl cd0 -F parent
sata0

# lsdev -Cl sata0 -F parent
sissas0

# lsslot -c slot
# Slot Description Device(s)
HEA 17 Logical I/O Slot lhea1 ent0
U789D.001.DQD52DG-P1-T1 Logical I/O Slot pci4 usbhc2 usbhc3
U789D.001.DQD52DG-P1-T3 Logical I/O Slot pci3 sissas0
U9117.MMA.6534BE4-V4-C0 Virtual I/O Slot vsa0
U9117.MMA.6534BE4-V4-C4 Virtual I/O Slot vscsi0
U9117.MMA.6534BE4-V4-C8 Virtual I/O Slot vscsi1
U9117.MMA.6534BE4-V4-C22 Virtual I/O Slot vscsi3
U9117.MMA.6534BE4-V4-C24 Virtual I/O Slot vscsi4

# lsdev -Cc cdrom -F "name physloc"
cd0 U789D.001.DQD52DG-P4-D1


Then from HMC -- go to --> Dynamically Logical Partitioning --> Physical Adapters --> Remove
Remove the controller and then assign to another partition.







Also: the other way
# lsdev -Cc cdrom
cd0 Available 03-08-00 SATA DVD-ROM Drive

# lsdev -C | grep 03-08-00
cd0 Available 03-08-00 SATA DVD-ROM Drive
hdisk5 Available 03-08-00 SAS Disk Drive
hdisk6 Available 03-08-00 SAS Disk Drive
sas0 Available 03-08-00 Controller SAS Protocol
sata0 Available 03-08-00 Controller SATA Protocol
ses0 Available 03-08-00 SAS Enclosure Services Device

ses1 Available 03-08-00 SAS Enclosure Services Device
ses2 Available 03-08-00 SAS Enclosure Services Device

NAME
reboot - reboot system or halt processor SYNOPSIS
#include <sys/reboot.h> int reboot(int howto, char *bootargs); DESCRIPTION
The reboot() function reboots the system. The howto argument specifies the behavior of the system while rebooting and is a mask con- structed by a bitwise-inclusive-OR of flags from the following list: RB_AUTOBOOT The machine is rebooted from the root filesystem on the default boot device. This is the default behavior. See boot(1M) and kernel(1M). RB_HALT The processor is simply halted; no reboot takes place. This option should be used with caution. RB_ASKNAME Interpreted by the bootstrap program and kernel, causing the user to be asked for pathnames during the bootstrap. RB_DUMP The system is forced to panic immediately without any further processing and a crash dump is written to the dump device (see dumpadm(1M)) before rebooting. Any other howto argument causes the kernel file to boot. The interpretation of the bootargs argument is platform-dependent. RETURN VALUES
Upon successful completion, reboot() never returns. Otherwise, -1 is returned and errno is set to indicate the error. ERRORS
The reboot() function will fail if: EPERM The {PRIV_SYS_CONFIG} privilege is not asserted in the effective set of the calling process. SEE ALSO
