I have a issue with tape driver and media changer which are not discovered by Netbackup, I followed the device configuration guide, many times, without success, I checked on Symantec forum, web, nothing helped me.
My configuration is the following :
Server : Sun Fire X4170 M2
OS : Solaris 10 x86, 8/11, 147441-13.
Tape Library : SUN SL48 SAS, 1 x LTO4.
Netbackup Server 7.1.
So when building the sg driver I'm getting the following error :
Yes, I did, (and rebooted with -r many times)
# You can describe a list of target port WWNs and LUN numbers which will
# not be configured. LUN numbers will be interpreted as decimal. White
# spaces and ',' can be used in the list of LUN numbers.
# To prevent LUNs 1 and 2 from being configured for target
# port 510000f010fd92a1 and target port 510000e012079df1, set:
I have more input from my configuration which shows that the tape drive is managed by the st driver, but when displaying the device path, it's not like st@target,LUN !!! and when building the sg driver we specify -mt target -ml lun, and in my case the target is something like a WWN for the FC devices !!!

Since few days, I found the following doc which is similar to my case, it states that the SAS 6G HBA are not compatible with the mpt_sas OS driver. and it says that the workaround is to disable the MPXIO, which is disabled in my configuration.
