thanks..I've read the documentation , not all 792 pages of it, but, if I can't get past 'insert disk 2 of VIOS Server' what good does reading ALL of the documentation do?
VmWare esxi and Oracle Vm server for Sparc do not require anything like a Virtual I/O server to provide virtual SCSI,Disk,network,etc, to an virtual machine. IBM ,to me,is completely backwards. why didn't they just make drivers that work out of the box without having to first install a virtual server to provide these virtual devices to LPARs?
I understand that one VM using a dvdrom , 'locks' it so that other VMs cant use it..and I'm sure I'm doing something wrong, but it shouldnt be as complicated as this when setting up multiple VMs.
and that's the reason I've posted a question here, in the hopes that someone could provide an idea of what I can do to get past this, to shed some light on it.
but replying 'read the documentation' isn't helpful. but thanks anyways.

IOSTAT(1) General Commands Manual IOSTAT(1)
NAME
iostat - report I/O statistics
SYNOPSIS
iostat [ drives ] [ interval [ count ] ]
DESCRIPTION
Iostat iteratively reports the number of characters read and written to terminals per second, and, for each disk, the number of transfers
per second, kilobytes transferred per second, and the milliseconds per average seek. It also gives the percentage of time the system has
spent in user mode, in user mode running low priority (niced) processes, in system mode, and idling.
To compute this information, for each disk, seeks and data transfer completions and number of words transferred are counted; for terminals
collectively, the number of input and output characters are counted. Also, each sixtieth of a second, the state of each disk is examined
and a tally is made if the disk is active. From these numbers and given the transfer rates of the devices it is possible to determine
average seek times for each device.
The optional interval argument causes iostat to report once each interval seconds. The first report is for all time since a reboot and
each subsequent report is for the last interval only.
The optional count argument restricts the number of reports.
If more than 4 disk drives are configured in the system, iostat displays only the first 4 drives, with priority given to Massbus disk
drives (i.e. if both Unibus and Massbus drives are present and the total number of drives exceeds 4, then some number of Unibus drives will
not be displayed in favor of the Massbus drives). To force iostat to display specific drives, their names may be supplied on the command
line.
