It appears that the Apollo file system will allow you to mount a disk without ACTUALLY creating a /dev entry to describe the device in the usual UNIX style... When we converted our DSP90's to 2500's we noticed this because during the transition, we had a 90 diskless to it's replacement 2500 and all the volumes on the 90 mounted into the 2500's file-system. We were using Aegis exclusively but the patch tape that fixed the bug stated that the bug could only be fixed if you used the /etc/mount command and not /com/mtvol! Upon diving in to the whole UNIX mount procedure we noticed that /etc/mount would say we had volumes mounted (ie /dev/dsk/W0d0s1, etc) but such a file does not exist in the /dev/dsk directory. Perhaps these 'phantom' disk devices are what the original poster is experiencing... Later, Phil :)
