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
Reconnect the cable.
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.
On all nodes, issue the following command to rescan the disks:
# vxdisk scandisks
On the master node, reattach the disks to the disk group they were in and retain the same media name:
This may take some time. For more details, see vxreattach (1M) manual page.
