DLT E 2/20 and SAN

[Domenico Viggiani]

I tried to connect a DLT E 2/20 (with two Ultrim drives) to a Brocade 2800 switch.
I see that switch port status is 'L'.
Quickloop is globally disabled.
Do need I to configure the specific switch port as Quickloop?

Thanks in advance for any help

Hi,

I am not familiar with this particular
model however, if there is a FC bridge
in it, (A4688A or A4689A) it needs to
be configured as fabric. Anything else
is not supported.

Hello Domenico,

Check the configuration of your library. For FC there is the possibilitiy to configure a 'HARD' loop id. If this is the case the unit will always be logging in as loop.

best regards,

Hello Domenico,

if you are using a 2/20 tape library with Ultrium tape drives you should have an internal FC bridge installed. Currently the use of an AL_PA is configured, therefore the FC port of the library logs into the bridge as L port (visible with switchshow command)

L-Port means loop port which can be either private or public.

Using quickloop for backup paths is not a good idea. I recommend you to use your Web GUI to change the bridge configuration as follows:
parameter hard AL_PA use: NO

The bridge will now log into the switch as N Port (you see the port with switchshow command as F Port). This is much more reliable for backups as a loop.

Be aware that you should contact your HP support for getting the latest drive and library firmware revision.

hope that helps

OK. Now I'm able to see libraruy as 'F-PORT' on the switch.

Thank you
