HPUX : Testing the disk status to identify the Health

Testing Disk :

 

 

# dd if=/dev/rdsk/c#t#d# of=/dev/null bs=1024k count=2048 (this will do a read/write test of 2048) # dd if=/dev/rdsk/c#t#d# of=/dev/null bs=1024k (this will do a full read/write test but will consume more time)

 

Here is an example

 

root@rx2620:> # dd if=/dev/rdsk/c#t#d# of=/dev/null bs=1024k count=2048

2048+0 records in

2048+0 records out

root@rx2620:> # dd if=/dev/rdsk/c#t#d# of=/dev/null bs=1024k

34732+1 records in

34732+1 records out
