FC/AL connection to tape library.

Is anyone using FC/AL to connect filers to tape libraries?

I am using Fibre Channel Arbitrated Loop (ie no switch) to connect my
filer running 6.2R2 to an ATL P3000 tape library.

When I first did this the filer could not see the tape drives until it
was rebooted (although it could see the FC bridge in the library a soon
as it was plugged in).

I just had to power cycle the library.  Now the filer can't see the tape
drives ("sysconfig -t" or "storage show tape" say "No tapes found.") but
it can see the FC bridge.

Is anyone else seeing this?  Is there any workaround, apart from buying
a switch or rebooting the filer every time the library is power cycled?

Re: FC/AL connection to tape library.

Thanks Pramod,

The online/offline worked fine.

I hadn't tried this before because it didn't appear to work when I first
installed the library.

Re: FC/AL connection to tape library.

You should run sysconfig and make sure of which slot the FC card that
is attached to the library is in.

Then, go into advanced user mode: rc_toggle_basic
and use the fcadmin tool to refresh the card.

For example, if the card is in slot 4, you
could do the following:

stimpy>rc_toggle_basic
stimpy*>fcadmin online 4 

This would re-init the card and look for devices attached to it again.
You can do this without rebooting the filer or interrupting service
to clients as long as the only thing plugged into the card is the
connection to the tape drive.

Hope this helps!

F740 thinks it's a C720, how to re-install?

Hi all,

We've got an F740 from another site where they tried upgrading it to
6.1.1 something, but now the system thinks that it's a NetCache C720
instead.

I want to upgrade it to 6.2R2, so I've downloaded the software and
created the boot floppies (all five of them) and used them to boot.  I
then initialized six of the disks on the system, and made a new
filesystem, but it still thinks that it's a NetCache.

Has anyone run into this before?  Any suggestions on how to change the
system back?

Thanks,
John

Re: F740 thinks it's a C720, how to re-install?

IIRC, there's a magic prom setting that sets the personality of the box.
I'm quite certain its hidden though (undoubtedly to prevent users from
taking advantage of price disaparities). I'd love to know how it got that
way, but support should be able to reverse it for you.

On the subject, and bringing up an old one, has anyone ever tried using
the three internal slots on a "C700/C800" head as root volume disks for an
F700/F800?

Re: F740 thinks it's a C720, how to re-install?

A quick update on my status here.  Unfortunately the system is not
under maintenance with NetApp, though we are going to work on getting
back under that before we re-deploy this F740.

I've opened up the case, checked the part numbers and it's really an
F740.  But even when I boot off the Diagnostics disk, it still insists
that it's an C720 and won't let me run DataOnTap as a NetApp properly.

I did do the following at the OK prompt:

  unsetenv netcache?

But that did not seem to make a difference.  Nor did re-flashing the
2.8a_2 firmware make any difference either.

Lots of fun, I'll play with this more tomorrow.

Thanks to the people who gave me the hint about the netcache? setting
in the PROM, it just didn't do much to help.

Thanks,
John

One of our resellers got motherboard replacement from NetApp and their F740
started to think that it is NetCache. I spent almost whole day on solving
this problem and only found that unsetenv netache? did the trick only for
DOT 5.3.x. After upgrade to newer system it again become NetCache. They
solved this problem by opening techsupp case with NetApp and got another
mainboard. Fortunately it was a demo system...

Hi,

Seen a lot of such messages in the log, what could be the reason?

[CIFSAuthen:info]: CIFS - password change failed. Will retry in 1 hour
