About Sony AIT drives on AIX
Sony S-AIT drives have DIP switches (SWA and SWB) located on the bottom of the drive.
For the NetBackup Shared Storage Option, you must set the SWA-1 (No Reply Unit Attention After Process Login) switch correctly. Its factory setting depends on the serial number of the drive.
If the drive has an early serial number, switch SWA-1 may be OFF. If so, change the switch to ON.
Drives with newer serial numbers have SWA-1 set to ON as the default.
These newer serial numbers are as follows:
SDZ-130 :01442007 and later
SDZ-130/L :01200696 and later
Also, for the drives that have a date of May 17, 2004 and later, the DIP switch is set to ON.
The following table shows the dip switch settings for the newer serial number drives.
