Server response time is too slow!

[Maria Pimentel]

Hi,
I'm having a problem with backup. Backup on this particular server (10.20) use to run 6 hours (full backup) now it's running 12 hours.
Any help, would be very appreciated. Like what to look for, network, etc..
Thanks,
Maria

Hi Maria,

If you are using a "Full Duplex" network connection, then make sure it is not set to Half Duplex. Use "lanadmin" to verify the card speed.

#lanadmin -x 2

Where 2 is the nmid of the lancard displayed through the command 'lanscan'. Use lanadmin with -X option to set the speed to full (lanadmin -X 100FD 2)

Look at the load of the system and also errors in /var/adm/syslog/syslog.log. A failed disk can cause your backup to hang forever. Application will notice it ofcourse.

More information would be helpful:

what type of backup software?
what type of devices and media?
What patch level?
Is it a network backup?
Is normal backups (tar, cpio, fbackup) works okay?

Check the system while the backup is running to make sure there are no other processes competing for resources. I had my backup time increase dramatically when a user decided to do his own backup at the same time as mine.

Hi Sri,

Thank you so much. It was running on half duplex, I changed to full.

Follow up:

The question at hand is WHY you were running half duplex.

If you manually changed it you are okay. If however the system booted this way, you need to take the following steps:

1) Check with the switch admin that the port your box is on is hard coded to 100 BaseT manual(explicit in the Cisco World). Boot your box after that, check lanadmin again.

2) If you notice you come up half duplex, you may have to hardcode hour chosen speed and duplex information into one of the following files.

/etc/rc.config.d/hpgsc100conf

or

/etc/rc.config.d/hpbtlanconf

I'm attaching my hpbtlanconf file as an example.

After this you'll need to boot.

The key in making sure this NEVER happens agains is being able to boot and come up 100 BaseT Full Duplex.

I'm still having problem with the card being on half duplex instead of full. Network admin checked it and it shows 100 full duplex, but every time the server reboots it goes back to 100 half duplex.
My question is, which file should I hardcode so it will stay on 100FD. I have 2 files in /etc/rc.config.d, one is called: hpetherconf and the other one is hpbasetconf. I'm enclosing the one that I changed, please any one, let me know if I made the correct changes and used the right file.

Thanks,
Maria

Hi Maria,

It depends on the type of the card you have. Post your server model and the type of card (HSC, PCI etc).

You should be modifying the hpbasetconf file not hpetherconf.

To verify if hpbasetconf is the correct file for your card, modify it and run the command while the speed is still set at 100 HalfDuplex

#lanadmin -x 1
#/sbin/init.d/hpbaset start

It shouldn't say "No BT cards found". Also it should set the speed to 100FD.
