HP StorageWorks Auto Path for AIX, v04.02 - Installation Guide (B7949-96005)

16 HP StorageWorks Auto Path for AIX: Installation Guide
Installation
Note: If dlmfdrv.unconf and dlmfdrv.conf do not exist, the DLM configuration manager
automatically creates the instances of the DLM devices for all of the disks supported by
DLM.
9. Start the DLM configuration manager.
# dlmcfgmgr
10. Verify that the DLM drivers (dlmfdrvn) and alert driver (dlmadrv) are
installed on an active kernel and available.
Example # lsdev -C | grep dlm
dlmfdrv0 Available HDLM Driver
dlmadrv Available HDLM Alert Driver
. . .
dlmfdrv1 Available HDLM Driver
dlmfdrvio Available HDLM Driver
In this example:
— dlmadrv is the special file name of the DLM alert driver.
— dlmfdrvio is the driver instance for internally managing Auto Path.
— dlmfdrv0 and dlmfdrv1 are the special file names of DLM drivers. Each
driver instance represents all paths to the same LU. The DLM driver name
does not relate to the hdisk or LU names. The instances start with
dlmfdrv0 and increment sequentially.
Verify that all DLM drivers representing the disk array LUNs you want
recognized are displayed. If one or more drivers are not displayed, AIX error
information is in the /var/DynamicLinkManager/log/dlmcfgmgr1.log file.
For details about the log file, see the AIX documentation.
11. Make sure a volume group is available.
If a volume group and file system already exists, see the HDLM
documentation for conversion of the volume group to a DLM volume group
then continue with step 14.
If a volume group did not exist before you started installing Auto Path,
continue with step 12.
12. Create a volume group.
To specify a physical volume group, specify the DLM device representing the
LU.
