Hello,

I have a HA storage and 2 HBAs and get lot of the "illegal request"
errors at computer boot time. For example, there are 2 LUN on the
storage.

The multipath software shows 2 active and 6 passive, total 8 devices.
The multipath mechanism works fine. But the computer's boot time takes
more then 4 minutes.

All errors're below. In addition, at the first opening of the computer,
delay time is too long.Â* I know the "illegal request" must be once.

These errors are repeated until dump by the kernel the "__ratelimit: 10
callbacks suppressed" message. In this way, the loop continues.Â*
