Silkworm - SN router3300 connectivity issue

[Mastan]

Dear All,

Brocade Silkworm 2400 8 port switch is connected to following devices.
1: HPrx2620 server
2: Hitachi San AMS500
3: SN router 3300 -> StorageTek l20 tape library

HP server to Silkworm switch two green leds are blinking, Silkworm switch to San two green leds are blinking and also I am I am able to see san Luns.

The issue is I am unable to access my StorageTek l20 tape library.

SN router to StorageTek l20 tape library is connected to SCSI cable.

In hp-server I am unble to see SN router and StorageTek l20 tape library.

Silkworm switch end two green leds are blinking and SN router3300 end one green led is blinking.

For your reference I have attached ioscan output.

Please guide me, how to resolve the issue!

Regards,
Mastan.

Hi Mastan,
I understand this is about SAN/FC switching,
this better fits in the storage/SAN forum instead of networking (lan).

The ioscan output from the host gives no information for this problem.

Did it work before? what has changed?
or is this a new configuration.

firts step is on the SN router check if this device can see the library.
does this router have aconsole port or web interface?

second step is the san switch
Post some output like "switchportshow"
or "switchconfigshow" on the sanswitch.

Dear Pieter 't Hart,

Thanks a lot for the suggestion.

SN router to StorageTek l20 tape library is connected to SCSI cable.

Silkworm switch to SN 3300 router connected FC cable.

Today I have removed both cables and connected the same and I have restarted the SN 3300 router after I am able to access Storage l20 tape library.

Thank you very much for the reply Pieter 't Hart.

Regards,
Masthan.
