Cannot umount file system...error Block device required

[Stefan Farrelly]

Either there is an error in your /etc/fstab file or youre not trying to umount properly.

eg. umount /SD_CDROM
or umount /stand

In your fstab file your entries should look like;

/dev/vg00/lvol3 / vxfs delaylog 0 1
/dev/vg00/lvol1 /stand hfs defaults 0 1
/dev/vg00/lvol4 /tmp vxfs delaylog 0 2
/dev/vg00/lvol5 /home vxfs delaylog 0 2
/dev/vg00/lvol6 /opt vxfs delaylog 0 2
/dev/vg00/lvol7 /usr vxfs delaylog 0 2
/dev/vg00/lvol8 /var vxfs delaylog 0 2

Thus if you now umount /home it will work fine. If instead your fstab file has the older /dev/... entries then ensure it says /dev/dsk/cxxxxx not /dev/rdsk.

Try fsck,if you can't umount /usr,/var,etc. boot in single user mode.
