Re: High load

[Aniruddh Singh <aps@jobsahead.com>]

Hi,

hdparm -tT /dev/cciss/c0d0p2 returns the following

/dev/cciss/c0d0p2:
 Timing buffer-cache reads:   2660 MB in  2.00 seconds = 1329.92 MB/sec
 Timing buffered disk reads:  248 MB in  3.00 seconds =  82.55 MB/sec

if i try to hdparm -I /dev/cciss/c0d0 it returns 
/dev/cciss/c0d0:
 operation not supported on SCSI disks

Do i need to installed sdparm and modify some settings?
