ALUA handles this automatically. If ALUA is not supported and you are using an MPIO environment, you
can use the dotpaths utility that comes with the Host Utilities to set the path priorities. If you enter
dotpaths without any options, it sets the priority for all Data ONTAP LUNs.
8. (PowerVM vSCSI environments) If you have LUNs presented to a VIO server from multiple third-party
storage vendors, make sure that all the LUNs use the same maximum transfer size.
Enter the following command: lsattr -El hdisk_name -a max_transfer
9. Display information about the LUNs and the HBAs by using the command sanlun. For example, to verify
that the host has discovered the LUNs, enter the command:sanlun lun show
If you are using multipathing, you can display information about the primary and secondary paths
available to the LUNs by entering the following command: sanlun lun show -p
Note: The sanlun command displays path information for each LUN; however, it only displays the
native multipathing policy. To see the multipathing policy for other vendors, you must use vendor-specific
commands.
