sg driver can't communicate with StorEdge C4

[nsaazn]

Hello!

After we update solaris 10 update 3 to solaris 10 update 5, sg driver can't adding C4 drives.

I've checked config files st.conf, sg.conf, st.links all looks fine. Both config files have entries with scsi target 2 lun 0 and target 3 lun 0 (tape drives). Both drivers are loaded, but sgscan all does not show tape drives. We tried to reinstall sg drivers, but without success.

Any ideas?

You say C4, presume this is channel 4, which does't show tape devices in cfgadm output you posted. So if that is the case you have an OS issue, not a NBU issue. First thing I would do is check the st.conf file, but copy it before you make any changes.
