Expand LUN
Hello all,
I have the following env:
* DS4300 storage SAN
* AIX 5.3 Lpar (storage through vio server)
* AIX 5.3 Server
Some FS are too small do I'm setting up a process to increase the size of the FS.
To expand the size of the FS I plan to do the following for the physical AIX server, because I have no free PPs in the VG.
1) Expand LUN on the DS4300
2) Run chvg -g <vg> on the AIX server
3) Run chfs -a size=+7G on the AIX server
4) Be happy with again a successful change
Can I use the same procedure for my AIX lpar?
The storage for the AIX lpar is assigned through a vios server. The backing devices for the disks in the LPAR are hdisks available in the vio server.
Is running chvg -g <vg> in the LPAR enough to have the new LUN size available in the LPAR? Does the vio server automatically pick up the new LUN size? Do I need to run something in the vio server as well?

tcp-env
tcp-env(1) General Commands Manual tcp-env(1)
NAME
tcp-env - set up TCP-related environment variables
SYNOPSIS
tcp-env [ -rR ] [ -ttimeout ] program [ arg ... ]
DESCRIPTION
The input for tcp-env must be a TCP connection. tcp-env finds out information about that connection, puts the information into several
environment variables as described in tcp-environ(5), and runs program with the given arguments.
Usually tcp-env is run from inetd. It might instead be run from another server that already sets up the right environment variables; if
PROTO is set to TCP when tcp-env is invoked, tcp-env assumes that all the other variables are set up properly, and it does not check
whether the input is a TCP connection.
OPTIONS
-r (Default.) Attempt to obtain TCPREMOTEINFO from the remote host.
-R Do not attempt to obtain TCPREMOTEINFO from the remote host.
-ttimeout
Give up on the TCPREMOTEINFO connection attempt after timeout seconds. Default: 30.
