I/O problem on HP9000 K class server

[mandar8377]

Hi,
I am facing I/O problem on HP9000 K series server having model 30
disk array attached to it. RAID5 is configured on the hardware level.
I/O is appro. half that of other server which
is having same configuration. I tried to diagnose thr cstm utility.
But it didnt give me any error messages for devices.

Can someone help me troubleshooting this problem ?
Thanks,
Mandar

Hi,
Like when I'm writing into my disks, its very slow. Iostat o/p is giving me 1.5 mb/sec. For ex. I'm creating dummy file on this server and checking i/o with iostat o/p. ITs apporx. 1/2 that of other server.
Thanks,
Mandar
