Solaris

After a bit os self-education:

Hmmm...I can't recall a physical SAN being capable of holding any sort of own "name", however a virtual SAN (VSAN), it is a bit different. VSAN is configured with these commands

Code:

MDS(config)# vsan database
MDS(config-vsan-db)# vsan 2 name DevUat

The name has to be uniqe across all connected switches.
so there is name identifier, I then looked for tagged frame format and found

http://www.t11.org/ftp/t11/pub/fc/fs-2/03-353v0.pdf
with the latter being more detailed.

The point is that inter-switch link does not carry information about VSAN name, only VSAN number, but this is not definitive, because VSAN name could have been exchanged during EISL estabilishement or later by quering the VSAN manager fabric-process.
Can someone put some light on (V)SAN names?

Hi All,

I'm running Solaris 9. The Version of VxVM is 4.2. I've inherited this system from someone else and there is no documentation for it. We have 5 NetApp filers. There are no volume names on the NetApp filers that even suggest it could be the two volumes mounted on the server.


I'll just get the WWNN from the server and see which Netapp filer it is attached to. Then the fun begins trying to find out on the filer which Volumes belong to that server

There is a command I found that did give me the name of the filer connected to one of our Solaris 9 servers.

vxprint -htrg diskgroup.

This returned the configuration of that disk group and the hostname of the filer it was attached to. This may have been put into the configuration by the admin who set it up though as it hasn't worked on any other server.

Hi Togr. I will have a read through those documents you sent on. Thanks for your help.

Thanks.

Wouldn't the LUN serial numbers or target numbers allow you to correlate the two? The WWNs should be enough to identify the physical Filer heads you are talking to.

gwhelan,
I believe reborg is right, WWNN should allow you to find a match between host and the filer.
Try the following command on Solaris:
> cfgadm -al -o show_FCP_dev <
this will show you WWN and LUNs visible from your server.
Going Veritas afaik
> vxdisk -e list <
shows Veritas disk names and system disk names.

On the filer it's easy, try the
fcp show initiator
lun show -m
igroup show

try

luxadm should be used with raw disk

/dev/vx/rdsk/ instead of /dev/vx/dsk

but I don't have a machine to try

but anyway

try

1. luxadm -e port

it will tell you the HBAs you have

then, take the restul and do

luxadm -e dump_map <the device path you get from above command>

this will give you the WWN numbers and thus you can know which SAN exactly you're on

Hi All,

Thank you all for your help. I'm sorry for the late reply as I have been out sick I will try those commands and let you know if they worked. Thanks again.

Hi All,

OK. I've managed to find out which filer I am attached to and the LUNs presented to my server. Thanks for all your help.
