Hi
We can test the SQL Server drives IO Performance using SQLIO tool.
The command used is
sqlio -kW -t2 -s120 -dM -o1 -frandom -b64 -BH -LS Testfile.dat
Here the drive used is M for IO Testing,
In our DC we are using SQL Mount points to mount the data, log and backup drives. so it has only one drive
In this how we can test the specific sql drive for IO testing
I have tried using the below cmd for sql drive by placing the testfile.dat in M:\Backup folder .. its showing error
sqlio -kW -t2 -s120 -dM \backup -o1 -frandom -b64 -BH -LS Testfile.dat
and
sqlio -kW -t2 -s120 -dM:\backup -o1 -frandom -b64 -BH -LS Testfile.dat
can you confirm what is the exact syntax to be used for doing IO test on Mounted SAN drives
