IBM ULT3580-TD3 tape drive issue

[Burak Topal]

Hi All,
There are 7 tape devices connected to our 11.31 server. It shows 7 tape devices connected but 4 of them shows NO_HW as S/W State. Rebooting the server did not solve the problem.

Any answer would be appreciated.
Thanks..

Above is the output of ioscan -fnC tape;

try below commands.

# ioscan -fun

#insf -e

# ioscan -fnC tape

Are they connected (via FC)..?

[Burak Topal]

Already run these commands.
Yes, connected via FC.
Thanks..

[Johnson Punniyalingam]

we need check the (FC) card

# ioscan -fnC fc -> post the output

(was there any activity done from the (storage switch side)

# dmesg
# /var/adm/syslog/syslog.log -> check for any (FC card failure or errors)

# /var/opt/resmon/log/event.log
