    SC_DISK_ERR2 is a problem accessing the disk down a given path but there can be several reasons for the error.

    Or you can go here:
    http://publibfp.dhe.ibm.com/epubs/pdf/c2343293.pdf

    Page 89 tells you how to decode it your self.

    After issue command

    connection type: fscsi0
    open dev: /dev/hdisk2

    Attempt to read reservation key...
    *> ioctl(PR_READ) error; errno = 16 (Device busy)

    *> ioctl(PR_READ) error; errno = 16 (Device busy)
    *> status_validity=0x1, scsi_bus_status=0x18
    xxx:/>

    We found something wrong with the reservation as this is standalone server.
    issue command "relbootrsv vg_name";shutdown -Fr ; pcmquerypr -Vh /dev/hdisk2
    Then, this problem fixed.
