Tachyon TL / B.11.11.09.Now rp8420 is having
Fiber card Tachyon XL with B.11.11.09.Luns on the VA7100 ate controlled through secure manager.When we set the WWN number of rp8420 for one LUN it is not getting detected in ioscan output. Please help.

Thanks in advance.

Pradeep,

Do you see NO_HW when performing a ioscan.

Can you attach the output of ioscan.

It looks like your SAn is not allowing the serevr to se the LUN, recheck your configuration

Make sure the lun has a correct WWN World Wide Name associated with it.

It must be the WWN from the fiber card on the rp8420 system.

fcmsutil /dev/td0 or whatever the actual device name, should be used to obtain the correct WWN.

Hi Steven,

I think you need to give the N_Port Port World Wide Name
