Appendix A.4 Differences in LU dynamic removal functionality

Depending on the HDLM version, LU dynamic removal functionality differs as follows:

In HDLM 05-02, 5.4

When Remove the LU even if there are Offline(C) paths is not specified (or when the following HDLM command is executed: dlnkmgr set -rmlu on)
If none of the paths connected to the LU are Online or Offline(C), the LU will be removed from being an HDLM management-target.

When Remove the LU even if there are Offline(C) paths is specified (or when the following HDLM command is executed: dlnkmgr set -rmlu on -force)
If none of the paths connected to the LU are Online, the LU will be removed from being an HDLM management-target.

In HDLM 5.5 or later

When Remove the LU even if there are Offline(C) paths is not specified (or when the following HDLM command is executed: dlnkmgr set -rmlu on)
If none of the paths connected to the LU are Online or Offline(C), the LU will be removed from being an HDLM management-target.
However, if one of the following conditions exists, the LU will not be removed from being an HDLM management-target:
- When an Offline(E) path connected to the LU satisfies the conditions for automatically switching to Online. For details about these conditions, see (2) Automatic switching of paths that have the Online(E), Offline(C), or Offline(E) status in Appendix A.3 Path status transition and automatic path switching.
- When Offline(C) paths are disconnected and changed to Offline(E) by an online operation, and then no path is Online

When Remove the LU even if there are Offline(C) paths is specified (or when the following HDLM command is executed: dlnkmgr set -rmlu on -force)
If none of the paths connected to the LU are Online, the LU will be removed from being an HDLM management-target. However, the LU will not be removed if any Offline(E) or Offline(C) path satisfies the conditions for automatically switching to Online. For details about these conditions, see (2) Automatic switching of paths that have the Online(E), Offline(C), or Offline(E) status in Appendix A.3 Path status transition and automatic path switching.
