You must apply MP2 or later when using the I/O fencing function. The I/O
fencing function can be used only when Hitachi USP, Universal Storage Platform
V/VM, or Virtual Storage Platform storage systems are connected in a Solaris 9
environment. Note that the only supported service group type is the failover
service group. The parallel service group and hybrid service group are not
supported.
#5
You must apply MP1 or later when using the I/O fencing function. The I/O
fencing function can be used only when Hitachi USP, Universal Storage Platform
V/VM, or Virtual Storage Platform storage systems are connected in a Solaris 10

3.1.4 Volume Manager Supported by HDLM
The following shows volume managers that HDLM supports.
„ When combining configurations by using VxVM
VxVM 4.1
#1
or VxVM 5.0

„ When combining configurations by using SDS or SVM
SDS 4.2.1
#2
, or SVM 1.0
HDLM-managed boot disks do not support a mirrored boot disk configuration
incorporating a volume manager such as SDS or VxVM. For this reason, you cannot
register an HDLM-managed boot disk in
bootdg
when using VxVM.
SVM supports the following configuration for HDLM-managed boot disks:
• OS: Solaris 10
• RAID level: Mirroring (no more than three mirrors)
• Cluster: None
