Let me clarify again. On the power machine which has physical FCs attached to SAN via SAN switch, as can be seen on my environment, there are 2 LPARs as below:
1. First LPAR with virtual FC (assigned by VIOS) and can use the LUN allocated to it, this point can be understood as it uses NPIV.
2. Second LPAR does not use VIOS and virtual FC, because with the lsdev -Cc adapter | grep fcs as showed, the FC adapter are "physical ones", not virtual as it does not start with C in the WWPN.
My question is, how can it connects and uses the LUN which is allocated to it? As my thought, it is utilizing also the physical FC port of power machine.
if first LPAR uses NPIV, so what technique does second LPAR use? It can use Power Machine physical FC directly and without need the VIOS and virtual FC?
Hi,
Is there a way to dynamically increase the size of virtual disk on the LPAR. The virtual disk is coming from my VIO Server. From my SAN I have allocated a disk to VIO Server and from VIO Server to my LPAR....If I increase the space of the logical SAN DISK (DS 4700 using IBM TotalStorage... (0 Replies)
Hi,
I want to know if there is any command which will tell me if an AIX machine is a LPar or not. I am using "lparstat -i" but it does not work on all AIX machines. Is there any generic command by whose output I will come to know if it is an LPar or not?
Please help.
Thanks,

Hello, we have a wierd and urgent problem, with a few of our p595 LPARs running AIX 5.3. The LPARs ran AIX 5.3 TL 7 and booted off EMC SAN disks, using EMC Powerpath. Every boot we run "pprootdev on" and "pprootdev fix". We can issue "bosboot -a" and we can reboot the machines.

Hi Guru, my question is that can I create LPAR in AIX 5.3, 6.0, 6.1 by using smit lpar, rather than using HMC or AIX Commands? Thank you very much. Mir Alihttp://xwww.unix.com/images/icons/icon5.gif (3 Replies)
I have login into a server, and when i launch this command uname -L.
I can see there is a LPAR.
But is there anymore commands i can use to get more information on the LPAR ?
like it is VIO ?
wat the IP address ?
etc, etc.
please help. Thank you. (7 Replies)

Hello,
I've set up email alerts on AIX Servers. so that i can get email notifications (via mail relay server) when ever there is abnormal behavior.
for example
1) my script monitors CPU/disk/memory etc... when it reaches high water ark, it will send an email alert.
2) disk usage alerts

close
close(n) Tcl Built-In Commands close(n)
__________________________________________________________________________________________________________________________________________________NAME
close - Close an open channel.
SYNOPSIS
close channelId
_________________________________________________________________DESCRIPTION
Closes the channel given by channelId.
ChannelId must be an identifier for an open channel such as a Tcl standard channel (stdin, stdout, or stderr), the return value from an |
invocation of open or socket, or the result of a channel creation command provided by a Tcl extension.
All buffered output is flushed to the channel's output device, any buffered input is discarded, the underlying file or device is closed,
and channelId becomes unavailable for use.
If the channel is blocking, the command does not return until all output is flushed. If the channel is nonblocking and there is unflushed |
output, the channel remains open and the command returns immediately; output will be flushed in the background and the channel will be |
closed when all the flushing is complete.
If channelId is a blocking channel for a command pipeline then close waits for the child processes to complete.
If the channel is shared between interpreters, then close makes channelId unavailable in the invoking interpreter but has no other effect |
until all of the sharing interpreters have closed the channel. When the last interpreter in which the channel is registered invokes close, |
the cleanup actions described above occur. See the interp command for a description of channel sharing. |
Channels are automatically closed when an interpreter is destroyed and when the process exits. Channels are switched to blocking mode, to |
ensure that all output is correctly flushed before the process exits.
The command returns an empty string, and may generate an error if an error occurs while flushing output.
