HP Serviceguard for Linux Certification Matrix, July 2014
HP ProLiant industry standard servers
Supported with HP Serviceguard for Linux A.11.20
Notes continued:
(9) Serviceguard for Linux A.11.20 supports SLES and RHEL’s distribution of Device Mapper multipathing (DM-Multipath) with HP Fibre Channel
arrays with the following restrictions:
a) Lock LUN is supported with DM-Multipath. If DM-Multipath is used with Lock LUN, it must be used for all nodes in the cluster.
b) Device alias names are allowed for Lock LUN, if configured, it must be used for all the nodes in the cluster and the alias name has to
be the same on all nodes.
c) From 11.20.20 onwards, SCSI3-Persistent Reservations (PR) is supported with Linux distributed Device Mapper Mulitpath. In prior
releases, PR cannot be used with SG/LX when DM-Multipath is enabled. Following needs to be taken into account if you are using
SGLX 11.20.00/11.20.10 releases:
i) When using DM-Multipath, SCSI3 Persistent Reservation must be disabled by setting a flag “FORCED_PR_DISABLE 1”
(without the quotes) in the cluster configuration file and apply the cluster configuration. This is the only way in case of Legacy packages.
ii) In case of Modular package, Serviceguard (Only in A.11.20.10) automatically disables SCSI3 Persistent Reservation, if it
detects multipath disk device. In A.11.20.00 Release, automatic disable feature is not available and one must not use PR module in the
package when DM-Multipath is used.
iii) SCSI3 Persistent Reservation should not be disabled in Serviceguard cluster if any node that is part of cluster, is a Virtual
Machine, being presented by a VMware ESX Server or in other words, DM-Multipath is not supported, if any of the nodes in the cluster
is a Virtual Machine. Please refer to “Using Serviceguard for Linux with VMware Virtual Machines” Whitepaper at
http://www.hp.com/go/linux-serviceguard-docs
iv) SCSI3 Persistent Reservation should not be disabled if any node in Serviceguard Cluster is a Virtual Machine. If disabled,
the configuration is unsupported.
(10) HP Storage EVA supported with firmware v3.01 or later.
(11) Supported with Red Hat with PowerPath 4.3.3 and above. PowerPath may be used for multipath and it is supported for LockLUN. If a version
of PowerPath earlier than 4.5 is used, search for article "emc137801" on EMC PowerLink at
http://powerlink.emc.com
.
(12) Any restrictions related to storage listed on
http://www.hp.com/products1/serverconnectivity/mass_storage_devices.html
apply to
Serviceguard for Linux as well.
(13) Disk monitoring is supported with Device Mapper devices.
(14) Moving from one kernel to another kernel version needs deadman driver rebuild in the kernel. Please refer to latest Managing HP
Serviceguard for Linux guide at
http://www.hp.com/go/linux-serviceguard-docs
(15) Please refer to HP Quorum Server support matrix at
http://www.hp.com/go/hpux-serviceguard-docs
(16) Serviceguard for Linux A.11.20.00 cluster having RHEL 5.8 nodes does not support Lock Lun due to change in behavior in RHEL 5.8 on ioctl()
over partitioned disks. This has been fixed in Serviceguard for Linux A.11.20.10 and HP recommends Customers to update to SG/LX
A.11.20.10 by applying SGLX_00339 (for RHEL 5) or SGLX_00340 (RHEL 6).
(17) Red Hat KVM Hypervisor is supported with the following configuration. Also, please refer to whitepaper “Using HP Serviceguard for Linux with
Red Hat KVM Guests” at

NOTE: Only iSCSI is supported
with above listed storages. XDC
is not supported with iSCSI.
Only
Quorum

supported.
Lock LUN
using iSCSI is
not
supported.
Serviceguard does not
have any specific
recommendation on
where/how the Guest OS
should be installed.
Please choose the boot
disk of Guest OS based
on RHEL 6 KVM
recommendation and
your requirement.
(18) Lock LUN is not supported on iSCSI device.
(19) When nodes are in mixed patch version, WWID for locklun device on Node- running SGLX-11.20.00 would mismatch with WWID of locklun
device on Node-2 running SGLX-11.20.10/11.20.20 even when the device is same. This is due to the way the WWID is read by
Serviceguard. Therefore, it will lead to failure of cmcheckconf and cmapplyconf of cluster configured with LockLUN as arbitration mechanism in
the mixed patch environment. This issue is applicable in RHEL only. Therefore, use “cmcheckconf”/”cmapplyconf” only after upgrading all the
cluster nodes to SGLX 11.20.20.
(20) When cmeasyinstall command (available only in DVD) is used to install Serviceguard RPMs from the DVD on SLES11 SP3 systems, the
command will exit saying that “ERROR: Unsupported Update for SUSE”. This has been reported in QXCR1001324026 and has been fixed
in SGLX_00469. Please download this patch from HP Support Center and use “cmeasyinstall” script located under “tools” directory of the
patch.
(21) Extended Distance Cluster (XDC) is not supported with any iSCSI storages that are listed in this document.
