desired kernel mode. If you switch the kernel mode from 32 bits to 64
bits when only the 32-bit version of HDLM is installed, you must reinstall
HDLM after the switch is completed. For details on how to switch the
kernel mode, see Switch the Kernel Mode on page 3-48 in Preparations
for a New Installation of HDLM on page 3-45.
• When installing HDLM on a host where a Device Manager Agent 5.0 or
later is installed, do not execute any of the following commands of Device
Manager Agent during installation:
hbsasrv, HiScan, hdvmagt_account, hdvmagt_schedule, hldutil, TIC
Notes on Related Software
• When using VxVM on the same host as HDLM, do not register any disk
groups containing HDLM devices in bootdg.
• When configuring a boot disk environment on a host that is using VxVM
4.1, and then executing a VxVM command such as the vxdisk list, or
vxdmpadm listenclosure all command, the enclosure type FAKE_ARRAY
is displayed for the boot disk but there is no problem. For details on this
phenomenon, see the Symantec documentation VERITAS Storage
Foundation(TM) 4.1 Release Notes Solaris Maintenance Pack 1.
• If you use the vxinstall program or the vxdiskadm utility to perform an
encapsulation while creating a disk group with an HDLM device or adding
an HDLM device to a disk group, the KAPL08019-E or KAPL08022-E
message might be output; however, this will not affect operations.
• Make sure that the version of HDLM is the same for all nodes on a cluster.
• HDLM and Sun StorageTek RAID Manager cannot be both present. Before
installing HDLM, remove Sun StorageTek RAID Manager. If either of the
following is applied, delete the /devices/devices link file by using the
following command, and then install HDLM:
¢
When removing Sun StorageTek RAID Manager
¢
When Sun StorageTek RAID Manager was previously installed and
the /devices/devices link file remains
# rm /devices/devices
For details on the /devices/devices link file, refer to the bug report for
Bug ID 4673499 on the My Oracle Support website. You need a My Oracle
Support account to view the bug report.
• For devices that can be managed by HDLM, you cannot use Sun
StorageTek Traffic Manager software (or, in Solaris 10, the Solaris
multipathing software MPxIO). If Sun StorageTek Traffic Manager
software (or MPxIO) is needed for devices that cannot be managed by
HDLM, you will need to separate HBA ports that recognize devices that
can be managed by HDLM from those that cannot.
#
In addition, for an
HBA port that recognizes devices that can be managed by HDLM, you will
need to disable Sun StorageTek Traffic Manager software (or MPxIO).
