Tape Writing Speedsiostat -cxn 5

or if you want to look after the fact you can grab my thuput script from =
my
website, http://www.NetBackupCentral.com

I also have a variation of that script that allows you to get performance
numbers for a client, or list of clients.  That's not on the site yet, I'=
ve
been very busy working on another project for the last several months, bu=
t
when that's done it should be updated.

If you want that client_thruput script let me know.

  Hi All



  DC v4.5
  1 Master , 2 Media Servers =3D solaris 8
  Robots =3D 2 Storagetek 9710 units with 9840 drives.



  Can someone give me some tips on how to see amount of data writing to t=
ape
(like the kilobytes written) column in the Datacenter GUI.

  Sometimes we need to dial in remotely with only cmd line to work with a=
nd
we need to work out if a backup job is still writing or if it has hung...=
so
being able to actually see data writing to the drive would be cool.

  It was easy to see in Legato but, I can't work out how to do it in
Netbackup (except for iostats which gives a very confusing output).

  Also any tips on measuring tape writing speeds would be most appreciate=
d.

  TIA for any help
