Notes on using a volume manager
Note the following when using a volume manager:
• Although disk partitioning and system backup functions are supported for
disks in a YaST2 system, the combination of YaST2 and LVM is not
supported.
• When you execute an LVM-related command such as pvscan or vgscan, a
CD-ROM IOCTL command might be sent to each device in the OS. The
IOCTL is available only for SCSI devices. You do not need to enter
information for the IOCTL when installing HDLM because HDLM devices
are not SCSI devices. HDLM rejects the IOCTL request and assumes that
the IOCTL processing has failed. The error message (KAPL05023-E) is
output to the syslog, but HDLM operations are not affected.
This message is also output in the following cases, but HDLM operations
are not affected:
¢
You execute the utility for collecting HDLM error information
(DLMgetras).
¢
The system is started.
File Systems Supported by HDLM
When using a file system, the related programs are as follows:
• ext2 (supplied with the OS)
• ext3 (supplied with the OS)
• ReiserFS(supplied with the OS)

Cluster Software Supported by HDLM
When you use HDLM in a cluster configuration, you must install the same
version of HDLM on all the nodes that comprise the cluster. If different
versions of HDLM are installed, the cluster system may not operate correctly.
If the HDLM Version and Service Pack Version, which are displayed by
executing the following command, are the same, the versions of HDLM are
the same:
# /opt/DynamicLinkManager/bin/dlnkmgr view -sys
