Systems may panic after GPT disk resize operation (3930664)

After you resize the GPT disks using the following command, you may experience a system panic issue, # vxdisk resize <disk_name> length=<new_size.This issue occurs if your deployment setup includes GPT disks partition.

No workaround available to resolve this issue. So you must not resize GPT disks, and to recover the system, wait for the system to restart.
