In Netbackup 6.5.x the nbftclnt service will fail to detect the "ARCHIVE Python" devices if the host has more than 100 /dev/sg devices. This is due to nbftclnt only scanning sg1 to sg99. There is an EEB available for 6.5.x that addresses the issue. The issues is formal resolved build NB_7.0.1_20100314.
How to detect the issue:
1: On the SAN client set the DEBUG logging
vxlogcfg -a -p 51216 -o 200 -s DebugLevel=6 -s DiagnosticLevel=6
vvlogcfg -a -p 51216 -o 137 -s DebugLevel=6 -s DiagnosticLevel=6
vxlogcfg -a -p 51216 -o 156 -s DebugLevel=6 -s DiagnosticLevel=6
2: Stop and start "nbftlcnt" services.
3: Capture debugging logging from the SAN client console.
nbftclnt -console –monitor
