vmunix messages

[Carme Torca]

Hi, I have seen in the /var/adm/syslog/syslog.log, this messages from vmunix.
It's something wrong?, What is the meaning?
Thanks!!
Carmen.
----------------
Dec 22 16:05:30 scs30 vmunix: td_create_domain_node: hw_path = ^D^D. For backward compatability domain
8 is not allowed.
Dec 22 16:05:30 scs30 vmunix: Configure the switch to assign a domain value other than 8.
Dec 22 16:05:30 scs30 vmunix: Domains > 8 will not be recognized till this problem is fixed.

Hi,

have a look here:

Id' say your hostname (/etc/rc.cofig.d/netconf) or domain name (/etc/resolv.conf) exceeds eight characters.

HP-UX doesn't like that at all.

Fix it and the message might go away.

hebron is okay as a hostname
hebron.juf.net is okay as a hostname

jerusalem is NOT okay as a hostname

hebron.investmenttool.com Is probably not okay as a hostname, but it can be done with the artful use of BIND 9.2.0 in the DNS database.

Hi Carme,

This looks to me like an fibre switch zoning issue.
The way the domains are zoned & presented to the fibre channel HBA are breaking a rule.

Also you might want to check if you have the latest Fibre Channel Mass Storage Patch - PHKL_27751:

HTH,
Jeff

[Ashwani Kashyap]

looks like your HBA is fabric enabled but the switch is not , it is still in private loop .

Domain ID of 8 is used for private or arbitrated loop , It is a reserved id . Dependng on the switch offset the fabric domain ID will be different .

For eg . for the hardware addrress :
8/12/.8.0 , 8=Bus_converter
12=Adapter
8=Protocol Type , reserved for private loop .

So if the switch is not operating in private loop mode and neither is HBA , change the domain ID of the switch form 8 to a value prefferably lower than 8 .

Hi,

And how I could see the path which is it?
At the ioscan, I couldn't see the .8 (??), How could I see if it's a disk??, or it's sure that it's a disk?

Thanks a lot of!!!
Carmen.

Hi,

check for a fibre switch with the domain id=8 and reconfigure it to another id.

greetings,

Michael

[Ashwani Kashyap]

YOur HBA's and ioscan looks ok and they are running switched fabric , as suggested by FCP DOMAIN protocol .

You will haveto look at the storage switch itself . What kind of switch is it and what is the domain id of the switch .

YOu will have to look at the switch management software to find the domain id of the switch .

If the domain id of the switch is 8 , then you will have to change that , because a domain id of 8 is reserved for arbitrated loop and should not be used for switched fabrics .

On changing the domain id , beware that all your disk device file will change and you will have to reimport all your volume groups again .
