HP-UX

Hey everyone this is my first post here, sure not to be my last

I'm working on an HP-UX (11i) machine and I'd like to add a partition to it, i need /bla/ which a certain megabyte size but i don't know how to do it, I can generally move around the os ok so im not completely illiterate,.. I know during installation it asks in a manger what partitions have what sizes/fixeddisks/range blablablah. You're answers are greatly appreciated!

Welcome! and have fun here!!!



Since I have just recently done this. it can be pretty involved.

Im not sure I could have done it without having watched someone else build a new partition first. And that was on a box that already had an Npar which we were converting to Vpars.

There is quite a bit of knowledge to absorb. Start here:

These are virtual partitions? I was looking more on the lines of just regular ones,.. im needing to throw one seperate just for specific software just to remain consistent really with some other servers,.. But I am reading through it thanks alot

ok so i figured the wonders of SAM out,.. and it seems i want to make a new logical volume and throw it in say /test/ , but now i only have so much disk space, is there a way to modify the other partitions in sam to maybe decrease the partition sizes?

Sorry I misunderstood your use of partitions... we dont use that word in relation to normal mountpoints. In HPUX partitions are typically used when partitioning a server into multiple OS instances.

I believe you meant a mounted filesystem (partition). If that is the case, then it is pretty easy to make one.

You need at least 1 disk available. You can name a Volume group anythign you wish and the Logical volume anything as well.

pvcreate /dev/dsk/cXtXdX
vgcreate /dev/vgXX
vgextend /dev/vgXX /dev/dsk/cXtXdX

lvcreate -n lvol /dev/vgXX
lvcreate -l #PE /dev/vgXX/lvol ## PE implies the default size of 4MB/PE ## lowercase ell

newfs -F vxfs /dev/vgtmp/rlvol
mkdir /mnt
mount /dev/vgXX/lvol /mnt

It is not advisable to reduce existing lvols as you can damage data on the mountpoint, the best way is to backup your data and then blow away and recreate the lvol.

You could move all data off the mount point and then reduce it, but better to start clean...

Also, I prefer not to use SAM, it can hang and screw you up. I use command line as I showed above. That way you are in control. And you learn the commands more easily.
