HP Matrix Operating Environment 7.3 and 7.3 Update 1 Infrastructure Orchestration User Guide

Excluding disks on a VM Host from the storage pool
For VM guests, use shared storage instead of storage that is only local to the host. This enables
efficient movement when the VM guest is moved to another VM Host. It is also a best practice to
isolate the backing storage for virtual machines on a separate drive from any storage containing
hypervisor system files, which results in greater performance.
Infrastructure orchestration services can be configured with the devices to be used for provisioning
VMs. Unless configured, IO considers all volumes on a VM Host for provisioning a virtual machine.
To exclude disks on a VM Host from consideration as a datastore for a virtual machine, do the
following:
1. Log into the CMS.
2. Navigate to the ..\Program Files\HP\Matrix infrastructure orchestration\
conf\hpio.properties file.
3. In the hpio.properties file, locate the following section:
##################### VOLUMES TO EXCLUDE #####################
# A semicolon separated list of volumes to be excluded for the
# list possible for allocation. They can be either VMware or
# Hyper-V style volumes:
# e.g. /vmfs/volumes/privateStorage; /vmfs/volumes/NotHere
# or C:;Y:;Z:
# An entry may contain one or more "*" characters which
# represent a wildcard and will match any character.
# comparison are case-insensitive.
# For example, if you had two volumes with Ids of
# "/vmfs/volumes/storage1" and "/vmfs/volumes/storage2" –
# you could exclude them both with an entry of
# "/vmfs/volumes/storage*".
# Note:
# This exclusion list applies to all hosts. So any host that
# is found to have a volume that matches an entry on the
# exclusion list - the volume will be removed and not reported
# as available to that host.
volume.exclusion.list =
4. To configure a Hyper-V VM Host, add the drive letters to exclude (for example, “C:;Y:;Z:”)
to the property volume.exclusion.list.
5. To configure a VMware VM Host, add the datastore path to exclude (for example,
/vmfs/volumes/privateStorage) to the property volume.exclusion.list.
6. Save the file.
7. Restart the Windows Service: HP Matrix Operating Environment infrastructure orchestration.
NOTE: Because the volume.exclusion.list values are treated as regular expressions,
some characters are interpreted to have special meaning, for example, backslash (\), question
mark (?), and brackets {}. To indicate that these characters should be treated as regular characters,
they need to be escaped with a backslash. Because a backslash is a special character in the
property file syntax, it has to be escaped as well.
For example, to exclude the volumes C:;Q:;\\?\Volume{1868cf92}, add the following line
to volume.exclusion.list:
volume.exclusion.list=C:;Q:;\\\\\\\\\\?\\\\Volume\\{1868cf92\\}
