[SunHELP] High Wait I/O( Average SAR Value %wio 25 to 35%)

[BINOY P.V]

Dear All,

We are facing High Wait I/O(SAR %wio 25 to 35% ) in our Database server 
running solaris 8 with oracle8i.

Dbase server is SunFire4800 with 12gb RAM,750MHZ*8CPU with 20gb swap space. 
We are using Veritas Volume Manger 3.1 and veritas Filesystem Manger3.4.

Ours is a SAN setup with 4T3's (each T3 is  36gb*9HDD) we are using RAID 
(0+1) Striped at hardware level and Mirrored at Volume Manager level.

Can anyone help us resolve the issue.

Thanks and Regards
Binoy
