disk environment on the HDLM device

Set up a device for the ZFS boot disk environment created in

Boot Disk

Environment that uses a ZFS File System on page 3-96

on the HDLM-

managed device.

If HDLM has not been installed on the device for the ZFS boot disk

environment, install HDLM. After installing HDLM, remove the device for the

local boot disk environment from HDLM management, and then perform the

procedure below.

For details on how to install HDLM, see

disk environment device is c2t50060E8010253334d0s0, and the HDLM

physical device is /devices/pseudo/dlmndrv@1/
dlmfdrv@w50060e8010253330,1:a.
# zpool replace rpool2 c2t50060E8010253334d0s0
