CDROM – DVDROM (Virtual Optical Device): Any optical device equipped on the Virtual I/O Server partition (either CD-ROM, DVD-ROM, or DVD-RAM) can be virtualized and assigned at any logical partition, one at a time, using the same virtual SCSI adapter provided to virtual disks. Virtual optical devices can be used to install the operating system […]

Increase rootvg dynamically If your rootvg “disk” is actually virtual, such as a SAN LUN or a logical volume on the VIO server, then it usually can be expanded on the SAN (or using extendlv on the VIOS) and then recognised on the AIX LPAR using the -g flag of the chvg command: chvg -g rootvg Note: this is supported
