?mne: RE: [Veritas-bu] iostat not showing tape stats - SLES 9...

 

Tape device stats aren't currently supported in the Linux distros that I've
seen - the instrumentation isn't there in many of the block device drivers.
I beleive this is also a limitation on HP/UX and some other BSD-derived
O/S's but I'm not sure on this.

 

If you're using SAN attached tape drives you can pull per port information
from your switches as a workaround, or piece together the stats from each
multiplexed stream over time.

 

Push your vendor to provide patches to enable iostat for block devices, and
to get them incorporated back into the base.

Subject: [Veritas-bu] iostat not showing tape stats - SLES 9...

Hi all,

 

I can?t get any stats from my tape drives on my SLES9 media server with
iostat, I have tried most options to iostat
 Is there other way to get the
tape stats? 

 

Thanks and regards,
