I've noticed that there a couple of threads from people having issues adding additional drives to a Solaris 10 install ( aside from the limit of of 2 extra drives, something to do with them being IDE ), but there doesn't seem to be any follow-up on them. I've also run into this problem on a 6/06 install ( 2Ghz MacBook, 2GB RAM, btw ). I've tried adding the additional drives before perfoming the install ( which hangs after it fails writing the VTOC to the first additional drive ), and also adding them to a working Solaris instance ( yes, I've reconfigured, etc ). Running format takes an age to list the disks ( all the while reporting drive errors to /var/adm/messages ). Interestingly, fdisk claims it cannot open the raw device, even though it exists. I'm wondering if this is limited to Parallels Desktop, as dd-b has managed to install an extra 2 drives using Parallels Workstation. At some point, I'll confirm this on my Win32 copy of PW. Anyone any ideas? Parallels guys?
