well that's the thing I read in other post that those are since the multipath is not started during bootup
but I just got home and I found these
kernel: printk: 20 messages suppressed.
kernel: Buffer I/O error on device sdc, logical block 0
kernel: Buffer I/O error on device sdc, logical block 0
kernel: Buffer I/O error on device sdc, logical block 14417919
kernel: Buffer I/O error on device sdc, logical block 0
kernel: Buffer I/O error on device sdd, logical block 0
kernel: Buffer I/O error on device sdd, logical block 0
kernel: Buffer I/O error on device sdd, logical block 14417919
kernel: Buffer I/O error on device sdd, logical block 0
kernel: Buffer I/O error on device sdf, logical block 0
and I left this system 4 hours ago and still getting these messages well those above are the only ones
I get the point during boot up even when the boot up process is slow because of those messages I don't know why while the server is up and running

is there a way to avoid multipath be sensing the passive paths?

NAME
hbaapi - Fibre Channel Storage Network Industry Association Host Bus Adapter Application Programming Interface (FC SNIA HBA API)
DESCRIPTION
The Common HBA API provides a consistent HBA standard interface for accessing information in a Fibre Channel Storage Area Network (SAN)
that would be implemented across vendors as a standard 'C' API supported by vendor specific library instances.
This API library is thread-safe, but threads should not be cancelled when execution is in the API.
The following functions are available in the API for managing a Fibre Channel HBA. This API would be exposed to upper level applications
to control SAN functionality.
Please refer to for details on structures used.
