In my system, I have HMC 7 with Power Machine 6 & 7. On the managed system, we have many lpars.
In some lpars, I can see they are using virtual fiber channel to connect to DS8K storage. In search with google, I understand that it is configured with VIOS server to share the physical FC channel with NPIV method.
But the situation is, in the same managed system, there are other lpars have physical FC, the WWpN not starting with C.
So my concern is, what method these lpars use to connect to SAN? How can they can "share/use" the physical FC without VIOS virtual FC?
lpar has virtual FC channel
Code:
[root@xxxxxx] / > lsdev -Cc adapter | grep fcs
fcs0 Available 02-00 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
fcs1 Available 02-01 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
fcs2 Available 04-00 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
fcs3 Available 04-01 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
fcs4 Available 06-00 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
fcs5 Available 06-01 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
Lpar has "physical" FC channel
Code:
[root@xxxxx] / > lsdev -Cc adapter | grep fcs
fcs0 Available 00-00 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
fcs1 Available 00-01 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
fcs2 Available 01-00 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
fcs3 Available 01-01 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
fcs4 Available 05-00 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
fcs5 Available 05-01 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
Both lpars below belongs to 1 power machine 6.
Please advise me on this situation.

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)

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.
