Can anyone tell me what is the maximum number of tape drives allowed is with SLES 10 and 11? I know with RedHat 4,5 and 6 the LINUX kernel limit is 128 tape devices. Is this true with SLES? I have heard it might be higher, such as 256. Any help would be appreciated.
This is probably handled by the kernel’s SCSI Tape (st) driver as
And so maybe this helps:
The tape driver currently supports 128 drives by default. This number
can be increased by editing st.h and recompiling the driver if
necessary. The upper limit is 2^17 drives if 4 modes for each drive
