        Can you post the first line of the sense data?

        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.

          I post the error data as below, and this alert had been fixed by command.
          After issue command
          xxx:/>pcmquerypr -Vh /dev/hdisk2
          connection type: fscsi0
          open dev: /dev/hdisk2

          Attempt to read reservation key...
          *> ioctl(PR_READ) error; errno = 16 (Device busy)
          *> status_validity=0x1, scsi_bus_status=0x18

          Attempt to read reservation key...
          *> ioctl(PR_READ) error; errno = 16 (Device busy)
          *> status_validity=0x1, scsi_bus_status=0x18

          Attempt to read reservation key...
          *> ioctl(PR_READ) error; errno = 16 (Device busy)
          *> status_validity=0x1, scsi_bus_status=0x18

          Attempt to read reservation key...
          *> 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.
