6. Run vxdctl enable to notify VxVM of the changes. 7. Verify the configuration of VxVM as shown in Example 3 "Verifying the VxVM configuration" (the output may be slightly different depending on your VxVM version and the array configuration). Example 3 Verifying the VxVM configuration # vxddladm listsupport all | grep HP libvxhpevale.so HP HSV300, HSV400, HSV450 # vxddladm listsupport libname=libvxhpevale.so ATTR_NAME ATTR_VALUE LIBNAME libvxhpevale.so VID HP PID HSV300, HSV400, HSV450 ARRAY_TYPE A/A-A-HP ARRAY_NAME EVA4400, EVA6400, EVA8400 # vxdmpadm listapm all | grep HP dmphpalua dmphpalua # vxdmpadm listapm dmphpalua Filename: dmphpalua APM name: dmphpalua APM version: 1 Feature: VxVM VxVM version: 41 Array Types Supported: A/A-A-HP Depending Array Types: A/A-A State: Active 1 A/A-A-HP Active # vxdmpadm listenclosure all ENCLR_NAME ENCLR_TYPE ENCLR_SNO STATUS ARRAY_TYPE Disk Disk DISKS CONNECTED Disk EVA84000 EVA8400 50001FE1002709E0 CONNECTED A/A-A-HP By default, the EVA I/O policy is set to Round-Robin. For VxVM 4.1 MP1, only one path is used for the I/Os with this policy. Therefore, HP recommends that you change the I/O policy to Adaptive in order to use all paths to the LUN on the primary controller. Example 4 "Setting the iopolicy" shows the commands you can use to check and change the I/O policy. Example 4 Setting the iopolicy # vxdmpadm getattr arrayname EVA8400 iopolicy ENCLR_NAME DEFAULT CURRENT EVA84000 Round-Robin Round-Robin # vxdmpadm setattr arrayname EVA8400 iopolicy=adaptive # vxdmpadm getattr arrayname EVA8400 iopolicy ENCLR_NAME DEFAULT CURRENT EVA84000 Round-Robin Adaptive Configuring virtual disks from the host The procedure used to configure the LUN path to the array depends on the FCA driver.
