Hi Oprakash,

Trying to read the disk with dd(1) completely
# dd if=/dev/rdsk/c#t#d# of=/dev/null bs=1024K

No I/O errors must be reported here.

Hi,

>>some dd command is used to check.<<

Example:-

dd if=/dev/dsk/c1t2d0 of=/dev/null bs=128k

output "record in & record out " should be same. (Than PV Looks Good)

>>Also i required a log files for the error report <<

Logs:-

/var/adm/syslog/syslog.log
dmesg
