Description Levente Farkas 2012-03-06 09:47:49 EST
until now (this means from rhel 5.0-rhel 6.1) both this command works:
hdparm -I /dev/sda
hdparm -I /dev/sda1
after rhel-6.2 the second is not working. the core reason is the 
ioctl(fd, HDIO_DRIVE_CMD, args);
kernel ioctl command which no longer works when called with the /dev/sda1's fd, but still working when use the /dev/sda's fd).

Since RHEL 6.3 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
