Restoring communication between host and disks after cable disconnection

If a fiber cable is inadvertently disconnected between the host and a disk, you can restore communication between the host and the disk without restarting.

To restore lost cable communication between host and disk

  1. Reconnect the cable.
  2. On all nodes, use the fdisk -l command to scan for new disks.

    It may take a few minutes before the host is capable of seeing the disk.

  3. On all nodes, issue the following command to rescan the disks:
    # vxdisk scandisks
    
  4. On the master node, reattach the disks to the disk group they were in and retain the same media name:
    # vxreattach

    This may take some time. For more details, see vxreattach (1M) manual page.
