Legato networker 7.5 sp1 using almost 100% cpu

[LioriK]

Hi All,

I'm using legato 7.5 sp1 on HP proliant 380 G4 with 4GB RAM.
My robot is adic i2000 with 4 drives.

When i'm starting full backup with 100 clients my cpu usage is almost 100%, the sessions on every tape is 12, 2 month before i used the same hardware and the same OS and i did't see 100% cpu useage.

Can you please advice?

I really don't know what to do.

Thanks, Lior.

Hi Lior, may be the %cpu usage is due to I/O wait. If you have more clients the I/O to the tape, or other media such a disk, may be greater and the %idle of the cpu's are minor.

I think you speaking about backup server

If you are using unix OS you can use top command to see it.


have you clients as Storage Nodes? they write directly to the jukebox and no load the I/O on the backup server.


On unix OS, like solaris, you can see the data transfer to any device with iostat command

If nothing of this happens, you can see the amount of cpu usage per proccess with top and see what proccess are using the CPU to identify the procces that high use the CPU.


I hope this help you

hi Mahalingam,

I'm using windows 2003 server on the backup server and my clients are not configure as Storage Nodes they are first speaking with the backup server.

hi Lior, i think you must need know what process have high usage of CPU. If the process is not a legato process you must check if this behaivor is normal.


You can see the amount of CPU per process with task administrator in your Win2003 server
