Can't see any connection on HSG80

I have a problem with my RA8000 connecting to my AS4100. I canâ t see any connection on my HSG80.

My SAN environment isï¼

RA8000/HSG 80ï¼ connecting to a San Switch 8.
AS4100/ Tru64 5.1B/KGPSA-CA, connecting to the San Switch 8

Switch led: steady green for 2 HSG connection ports,
Yellow for the port connecting KGPSA-CA when AS4100 in normal console >>> but it turns green when AS4100 is in diag mode or when tru64 booted.

The detail status info is in the attachment.

I do appreciate your kindly help!

Re: Can't see any connection on HSG80

How about zoning on the SAN Switch?

Re: Can't see any connection on HSG80

Hi Paul,

As Stephen suggests, what do you see on the SAN switch ?

If you telnet on to it, can you see the WWNs of the HSG80s and the KGPSAs when you issue the switchShow command ?

If you can, check whether any zoning is configured, which is limiting the access of the 4100 to the HSG80s. cfgShow

Hope this helps,

Regards,

Re: Can't see any connection on HSG80

I'm sad that I don't have admin password for switch. Its default password is changed.
Is there any way to reset the switch to its factory default?

By the way, what're detail orders to have HSG80 creating connections automatically? I mean steps about turning on device/server power, plugin into switch, and etc.

Thanks in advance.

Re: Can't see any connection on HSG80

Hi Paul,

Have you tried logging in with admin/password and root/password

These were the defaults. If they have been changed, then it can be 'interesting' to get them reset...

Cheers,

Re: Can't see any connection on HSG80

Forgot to say, that you can see if there's any zoning configuration in place by pointing your web browser at the IP address of the switch - default is 10.77.77.77.

The initial webpage displayed has a line somewhere near the bottom which tells you name of the active configuration, IIRC.

If you don't know the IP address you'll have to hook up the serial console, and look at the output whilst the switch is booting.

Re: Can't see any connection on HSG80

> By the way, what're detail orders to have HSG80 creating connections automatically?

The HSG needs to receive a 'Fabric event' to do that automatically. Usually, a server reboot and/or a scan via WWIDMGR is sufficient.

However, from the output of
P00>>>wwidmgr -show port

it is apparent that the AlphaServer does not 'see' the HSG ports. It could be a switch zoning issue as has already been suggested.

It could also be a lack of LUN 0. The HSG is running in SCSI-2 mode with the CCL being disabled and it is not obvious if you have a Unit 'D0'.

What version of Tru64 Unix is running on the Alpha? Or is there another reason you don't use SCSI-3?

Re: Can't see any connection on HSG80

Hi Paul,

You might also want to check the firmware revisions on the HSGs and the KGPSA.

The version of ACS on your HSG80s (8.5-0) is very old. That *might* be causing you problems...

Re: Can't see any connection on HSG80

I try your suggestions above, but fail yet.
I modify the switch's IP and use web to check it. But I can not check its zoning info as both default admin and root passwords have been changed (not password).

Is there any way to bypass login, or do factory reset, or reload its firmware without any password?

Here's my KGPSA version in my tru64 booting log,
Aug 21 17:02:39 keditru64 vmunix: KGPSA-CA : Driver Rev 2.06 : F/W Rev 3.92A2(2c

As for ACS version, I think 8.5F should supports the FC SAN swicth 8 and AS4100.

Re: Can't see any connection on HSG80

Hi Paul,

Do you have another SAN switch that you do know the admin password for ?

If yes, then there's a utility on Brocade's website that will allow you to reset the passwords - assuming that the version of FabricOS on the locked out switch is high enough... I'll dig out the details later.

If you don't have another SAN switch, then the only way is to get hold of a special switch specific firmware from Brocade (probably via HP) that allows the passwords to be defaulted. However, if your switch is out of support, then getting hold of this firmware can be difficult - if impossible in my experience.

Hope this helps,

Re: Can't see any connection on HSG80

Yes, I have another switch which I've password. Its firmware version is 2.6.0. And I the FW CD.

The FW for the siwtch without password is 2.6.0c and 2.6.0h.But I remember firmwareDownload can only be done after login. Is there any way to do firmware update while bypass login?

Re: Can't see any connection on HSG80

Hi,

OK. You can get the PasswordReset utility here:

http://www.brocadeconnect.com/content/Connect%20with%20Users/Share%20Scripts%20and%20Utilities/passwordReset.jsp?cat_id=66669472

This will however require a login onto the Brocade Connect website - these are free though. Just register with the WWN of one of your switches.

However the minimum firmware version is listed as 2.6.0d. I'm not sure from your last post whether you have this or not...

If you are lower, it is possible to boot the SAN switch from firmware on an FTP server. However I'm not sure whether this will allow you to reset the passwords...

Re: Can't see any connection on HSG80

Thanks for all your suggestions, esp Rob's step by step help. It's zoning configuration preventing connecting.

Re: Can't see any connection on HSG80

After deleting zoning, it's OK.
