hello all -

I have had some assertive answers for my query and have concluded ( as
an admin ) :

'8' cannot be exceeded without an additional software like Veritas
Volume Manager.

But, my client would not go for this ( although he has the s/w , does
not have license for non-ssa disks ). Instead is planning for multiple
4gb disks in lieu of 9gb ones which he is yet to order.

Many thanks to all who responded which include ( some of their comments
too ) :

-said- In this case I would add one more disk and create the new
partitions on ths new disc.

-said- Not without Veritas volume manager. Sorry. On the bright side
VxVM is a nice product that seamlessly provides this functioanlity.

-said- No. The physical disk drive is minor-number/8; the partition is
minor-number%8. This is hard-wired in the disk driver, and possibly
other parts of the kernel. I've only seen it different in HP-UX, where
they changed it from 8 to 16, and in Linux, where it's 64.

Special thanks to and who
gave me some insight to the issue.

My query was -

thanks again,
