Hello,

Is there a way to run the chdev command for all disk devices on a host,
instead of running for individual devices.

For eg,
chdev -l hdiskx -a reserve_policy=no_reserve

changes the reserve_policy for hdiskx to no_reserve.

Can I use a single command to change the reserve_policy of two or more disk devices to no_reserve?

Thanks,
Kannan

I dont think there is a single command to achieve this. Maybe you can try this:

for i in `lspv | awk '{ print $1 }'`
do
chdev -l $i -a reserve_policy=no_reserve
done

This would change the attribute for all the disk drives. Maybe with a little grepping you could filter out a bit.
