Hello all I hope someone can help me with this. I have a single LPAR which is supplied a rootvg and datavg disk set from a dual VIO server configuration. I see dual path disks for all the datavg disks but only see one path for the rootvg disks.
The client LPAR has the following:
But when lspath is run the following is returned:
As can be seen FCS0 (fscsi0) is missing. From the VIO server which is serving this adapter you have:
When I run the map command I get the following:
This is where it gets interesting on the offending vfchost it can be seen that only 1 port is logged in, whereas on the working port 2 are logged in.
I believe this is the problem but cannot find anything on a general internet trawl to answer why! I believe it is a SAN configuration problem but need evidence with which to beat up the SAN team!
The simple answer is yes they are as follows:
The available adapters are:
FCS0 is from the first VIO with the partner adapter FCS2 from the second VIO
The adapter plus children are as follows:
The adapter from the other VIO server:
After a lot of work finding the connection infromation of the offending disks and using the
and
command I finally convinced the SAN team that something was not behaving itself on the SAN switch.
A full reset was then run on the switch with all VIO servers and the client LPAR powered off. Once the switch reset had finished I rebooted the VIO servers and the client ran an
which showed all disks!
It appears that the
do not actually do anything on the fibre link between the HBA and the switch. I believe I will never find out why the ports dropped!
Please forgive me here as I don't fully understand what I am talking about here so if I use the wrong terminology please overlook me.
We have multiple AIX LPARs on the managed system with two VIO Servers. A Co-Worker and I are trying to set up a new LPAR client (The guy that knows this is out)... (14 Replies)
Hi All :)
i would like to know if i can customize the WWN of the new VFC (NPIV).
Or, if i must move the LPAR on another server with another FCS, i have to change the zoning??
Thanks in advance.

Hello,
I am using fgltty connection (which is actually qputty) to my AIX 6.1 server.
The problem is that PageUp and PageDown keys are not working and i cannot find a way to do the correct mapping for this issue. I read and tried many things that i saw in the web but nothing worked. Well... (2 Replies)
Hi,
I want to change from vscsi to npiv. Is it possible to use both on the same adapter, so we can change the systems one by one, or must we place a second FC adapter in the VIO servers?
Thanks,

Hi All..
On to a new implementation with AIX 7.1 san boot from EMC disks (Using NPIV). Anyone played with this recently?
Wondering if we need PowerPath on the AIX clients or has native MPIO matured to replace it. Thoughts?
Thanks

Hi All,
I'm preparing to migrate some servers from vscsi to pass-thru NPIV. I am planning to have the SAN team move the exact LUNs from vio1/vio2 to those two VWWN through NPIV.
My question is on the partition itself.. right now, let's say I have hdisk0/1/2/3/4 that are part of datavg. They... (2 Replies)
Is anyone here using NPIV with AIX? If you are, what type of switch are you connected to? Also, please share some impressions of NPIV over traditional port-to-port LUN assignments. We are looking to move to NPIV and need some convincing argume... I mean information. (2 Replies)
Hello guys,
It would be so nice of you if someone can provide me with these informations.
1) My SAN group assigned 51G of LUN space to the VIO server.I ran cfgdev to discover the newly added LUN. Unfortunately most of the disks that are in VIO server is 51G. How would I know which is the newly... (3 Replies)
