Hi justin
AIX has better volume management than solaris.You can play with disks in
AIX 'coz of LVM.If you are only working with Solaris ( without Disk Suit or
Veritas ) , then you are gonna a football player playing test cricket
match.
A.don't bother about the tags you see in the format Utility.Its only the
slice number that counts when you are creating filesystem.You can change
the tag names as u wish by selecting that slice number in partion table of
format utility.
B.You can have the different filesystem names
C.If you are using Veritas you can increase the filesystem size
dynamically.If not your hands are tied.Filesystems can't span multiple hard
disks.You have to take the back up of old filesystems, partition the disk
again with the sizes you want and restore back the old file systems

I'm sorrrrrrrrry guys!!!. I know this is an AIX forum and I'm an AIX guru
myself but I have a few really basic and perhaps inept Solaris questions
for any Solaris admins out there:
1.) I'm reading this Solaris beginners admin guide, here are I'm reading
about partitioning a new disk with this format utility. Do you need to
configure a root partition tag even on additional disk? I can see on the
primary disk that tag(root) is configured as the actual "/" filesystem.
They also have an example on an additional external disk where they have
root on it as well. This confused me. Now I know in AIX you can have the
root logical volume/partition span multiple hdisks/disks. That's why I saw
root on multiple disks at first but it turned out that these two disks had
nothing to do with one another neither do the partitions. Any input onto
why all disks on this system has a "root" partition tag would be
appreciated.
Also question b on the same subject would be, does the partition tag have
anything to do with the actual filesystem name? Or can I have an oracle
filesystem/mount point called: "/oradata" on a "/usr" partition tag?.
question c is when you repartiton disks like add space or change the
starting and ending point of a partition on these systems. Do you need to
reboot the system after you save and label the table or is it automatic.
Also it says any partition modification will wreck the filesystem/data
which resides on it. It says you should back it up first. Does any
partition modification include expanding it?. I know in AIX you can expand
on the fly via: "chfs" without a reboot.
question d How do you handle modifying system partitions such as the
partitions which: "/", "/tmp", "/opt", and "/var" reside on?. I'm assuming
they can't be modified except for either a new installation of the O/S, or
through a single user mode boot and a "/newroot" mounting method?.
Please advise. I hope it's not too confusing. Again I'm a beginner so go
easy on me. I live and die by AIX but coming over to the DARK SIDE a bit.
thanks!.
