Re: [Veritas-bu] Strange speed problem...not the norm

2006-11-02 Thread Clooney, David
In my experience in your scenario almost  always boils down to
Auto-negotiate somewhere along the line.

Try using bpbkar on the client writing the same data as to be backed up
to a null device , this way you can determine without network, tape
,blah blah.
That the bpbkar process is in actual fact reading the data quick enough,
if this succeeds def network prob somewhere.

Check the performance tuning guide for more detail.

Has anyone seen this before?

Netbackup 5.0 mp3 Solaris9 connected to L700 via fibre.

I have a network client on a 100Mb network which is beyond slow backing
up. Looking at the gui ( i know not accurate ) details for a job shows
like 127kb/s.

Doing an scp of a 128mb file from master server to the client is quick 
20 secs.
Doing an scp of the same file from client to master it gives ETA of over
an hour, which comes down to like 20-30 minutes. Obviously wrong.

So first thing on the solaris client i did was force the nic to 100 full
autoneg off. Then doing an scp seems to be quick both ways. Great.

Then launch a manual backup off for the client only and the speed is
slow. 127kb/s again.

going back and trying the scp is now slow again from client to master
server.

Whats going on?

Sounds like a weird network problem to me, check switches/etc, run a 
constant FTP and see/wait/watch to see what changes when it goes slow

I'm with David on this.  You changed it on the server but did the
associated switch port get changed as well?   Both sides should be hard
set to 100 Full.

Re: [Veritas-bu] Strange speed problem...not the norm

2006-11-02 Thread Paul Keating
Check the status of the NIC before just setting it to FULL.Maybe it was FULL to 
begin with and you're just looking at a RedHerring.
Check for CRC errors and link status on the client NIC, server NIC, andevery 
switch/router port in between.
If some device is misconfigured, start a BIG ftp, and watch it..thenfix the 
network config, and then monitor that to see if it flips back.
In most cases, a duplex problem will only show up if one of two ends 
ishard-coded.hard coding NIC speed and duplex is old 
school...GetEVERYTHINGevery single port in your environment set to 
auto-auto andyour problems will go away.We've slowly got everything here 
fixed...the only issue we have no isif someone ghosts a new system with an 
old image, or someone fixes alink on the fly, but there's an old rc script 
hanging around that hardcodes the connection again after a reboot.
GigE does not do proper flow control if you hard code...most switchesand NICs 
will not allow you to set a Gig connection to auto-duplex,unless you exploit 
a bug, like some Cisco IOSs you can't set Gig-FULL,but if you set 100-FULL and 
then change speed to Gig, the FULL hangsaround...bugour network guys were 
exploiting that on purpose foryears...
Sorry, that's my auto-neg rant for this month.

Does the traceroute from master - client and client - master show the same path.

If yes then its really complex, if no then check whethther any segment
in between has been a victim of broadcast or huge data transfer.

There is Symantec tool provided by support, run and send the output to
support, and it seems they would quickly tel u the reason.

 Subject: [Veritas-bu] Strange speed problem...not the norm Has anyone seen this before? Netbackup 5.0 mp3 Solaris9 connected to L700 via fibre.
 I have a network client on a 100Mb network which is beyond slow backing up. Looking at the gui ( i know not accurate ) details for a job shows like 127kb/s.
 Doing an scp of a 128mb file from master server to the client is quick  20 secs. Doing an scp of the same file from client to master it gives ETA of over an hour, which comes down to like 20-30 minutes.
 Obviously wrong. So first thing on the solaris client i did was force the nic to 100 full autoneg off. Then doing an scp seems to be quick both ways. Great.
 Then launch a manual backup off for the client only and the speed is slow. 127kb/s again. going back and trying the scp is now slow again from client to master
 server. Whats going on? ___ Veritas-bu maillist-
