Re: NIC Settings

Geoff,

You are getting the runaround.

Our Solaris admins use this script on solaris 2.6 to determine NIC settings. 
The key command is ndd -get.

Will a Solaris expert please tell me if this is true?

We are having an issue with backup speed on a Solaris server. I posted the
question yesterday but did not hear anything except what I already have been
told, i.e. make sure the duplex is matched properly. The Solaris server we
have is reporting running OS 5.8 and TSM 5.1.1.0, compression has been
turned off.

When I asked for the NIC/switch setting to be verified the answer I got back
was they don't do that on Solaris, on the host side. I would like
verification please. This computer backed up just over 2GB of data in 9.5
hours and at this point I don't know what else to have checked. The 10GB
they have would have taken 4 days at that rate.

I refused to call Tivoli till I get answers to the questions I've asked
here. I have no answers, yet they still want me to call so Tivoli can tell
me to check the same things I don't have answers to.............go figure.

Could someone either straighten me out or shed a little light please? Will
making any changes to the options file help?

Thanks as always for the help.
