Slow Throughput
host apdater= 1 (system has 2
factory installed adapters)
SCSI Bus #= 0
Target ID= 6 (factory default)
Lun #= 0
The kernel was rebuilt and the system rebooted. Everything was fine.
The backup command used was:
tar cvf /dev/rStp0
The backup proceeded perfectly, except it is very very slow, and not even close to stated specs for this drive. This is totally unacceptable. This is about 140k/sec. The data is stored on Compaq Hot Pluggable 18GB 10k drives, running raid 1 (mirroring).
I would appreciate any responses as soon as possible.
Thanks,
John Stroker

Re: Slow Throughput
Changing block size and buffer in the Tapesvr.cfg under sys:\arcserve.6\nlm
for DLT tape use block size=5. This work for me. Double the output speed.

Re: Slow Throughput
What helped at our site was fixing the NIC at 100Mb/half duplex. Make sure the port on the switch and the NIC in the backup server is configured the same way.Ciao, Koen

Re: Slow Throughput
tape -a 1024 setblk
Will set a fixed 1k block size.
The problem relates to variable block size - there are several articles on the SCO webiste concerning this.
For other operating systems - if you're using a backup software program, check with the vendor - for example arcserve has a configuration file (tapesrv.cfg) that allows setting of block size and other paramaters. More info would be available from the software vendor tech support.
