Problem What to do
when the DLMgetras utility for collecting
HDLM error information was executed.
• When installing HDLM in Windows Server 2008 or Windows Server 2012,
perform the following operation before the installation to make sure
applications cannot access the HDLM management-target disks.
¢
If the disk is not used as a cluster resource:
In the Windows' Disk Management windows, offline the disk.
¢
If the disk is used as a cluster resource:
Stop Cluster Service.
• Windows Server 2008 or Windows Server 2012 supports user account
control (UAC). If you are logged on with a non-administrator account, use
the Administrator: Command Prompt window when executing any of
the following programs to install or remove HDLM:
¢ setup.exe
#
¢
installhdlm (installhdlm utility)
¢ removehdlm (removehdlm utility)
#
This program can also be executed using Run as administrator.
• If you are using Hyper-V in Windows Server 2008, you cannot use HDLM
on a guest OS. Install HDLM on a host OS.
If you want to install or remove HDLM on a host OS, first terminate the
Hyper-V manager console. If the Hyper-V manager console is running,
the installation or removal of HDLM will stop. If this happens, you can
continue with the installation or removal of HDLM by first terminating the
Hyper-V manager console.
• If you are using Hyper-V in Windows Server 2008, you cannot use a
cluster environment on a guest OS.
• If you are using Hyper-V, unallocate the physical hard disk of an HDLM
management-target device that you have allocated to a guest OS before
you perform an installation, upgrade installation, or removal of HDLM on a
host OS. Then, after the installation, upgrade installation or removal of
HDLM on the host OS, allocate the physical hard disk to the guest OS
again.
Notes on Related Software
• Do not install any multi-path management software other than HDLM. If
multi-path management software other than HDLM has been installed on
the host, remove the software, and then restart the host before re-
installing HDLM.
• You cannot use HDLM for Windows and HDLM for VMware on the same
host.
