Example 4 Setting the I/O policy # vxdmpadm getattr arrayname EVA8100 iopolicy ENCLR_NAME DEFAULT CURRENT EVA81000 Round-Robin Round-Robin # vxdmpadm setattr arrayname EVA81000 iopolicy=adaptive # vxdmpadm getattr arrayname EVA8100 iopolicy ENCLR_NAME DEFAULT CURRENT EVA81000 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. For more information, see "Installing Fibre Channel adapters" (page 50). To identify the WWLUN ID assigned to the virtual disk and/or the LUN assigned by the storage administrator: • Oracle SAN driver, with MPxIO enabled: ◦ You can use the luxadm probe command to display the array/node WWN and associated array for the devices. ◦ The WWLUN ID is part of the device file name. For example: /dev/rdsk/c5t600508B4001030E40000500000B20000d0s2 ◦ If you use luxadm display, the LUN is displayed after the device address. For example: 50001fe1002709e9,5 • Oracle SAN driver, without MPxIO: ◦ The EVA WWPN is part of the file name (which helps you to identify the controller). For example: /dev/rdsk/c3t50001FE1002709E8d5s2 /dev/rdsk/c3t50001FE1002709ECd5s2 /dev/rdsk/c4t50001FE1002709E9d5s2 /dev/rdsk/c4t50001FE1002709EDd5s2 If you use luxadm probe, the array/node WWN and the associated device files are displayed. ◦ You can retrieve the WWLUN ID as part of the format -e (scsi, inquiry) output; however, it is cumbersome and hard to read. For example: 09 e8 20 04 00 00 00 00 00 00 35 30 30 30 31 46 45 31 30 30 32 37 30 39 45 30 35 30 30 30 31 46 45 31 30 30 32 37 30 39 45 38 36 30 30 35 30 38 42 34 30 30 31 30 33 30 45 34 30 30 30 30 35 30 30 30 30 30 42 32 30 30 30 30 00 00 00 00 00 00 .........50001F E1002709E050001F E1002709E8600508 B4001030E4000050 0000B20000 ◦ The assigned LUN is part of the device file name. For example: /dev/rdsk/c3t50001FE1002709E8d5s2 You can also retrieve the LUN with luxadm display. The LUN is displayed after the device address. For example: Oracle Solaris 67
