Install the driver and HBA card. Refer to the documentation from the vendor for instructions.
After you physically add shared disks to the nodes, you must initialize them as VxVM disks and verify that all the nodes see the same disk. Use the example procedure; see the Veritas Volume Manager Administrator's Guide for more information on adding and configuring disks.
==============================================================
See the Veritas Volume Manager documentation for details on adding and configuring disks.
In the following example, a disk with the AIX device name /dev/rhdisk75 is identified by VxVM as EMC0_17:
# vxdmpadm getdmpnode nodename=hdisk75
NAME STATE ENCLR-TYPE PATHS ENBL DSBL ENCLR-NAME
============================================================
EMC0_17 ENABLED EMC 1 1 0 EMC0
Notice that in the example command, the AIX device name for the block device was used.
You can, as an option, run the command vxdisk list
vxvm_device_name to see additional information about the disk, including the AIX device name. For example:
For more information see the Veritas Volume Manager Administrator's Guide.
vxdisksetup
command to initialize a disk as a VxVM disk.
vxdisksetup -i device_name format=cdsdisk
The example specifies the CDS format:
# vxdisksetup -i EMC0_17 format=cdsdisk
Repeat this command for each disk you intend to use as a coordinator disk.
