Multipath Configuration using Native Multipath

8.2
Multipath Configuration using Native Multipath
"Native Multipaths" is an OS function available for HP-UX11iv3 onwards.
Native Multipaths can be used to set the I/O load balance policy (load_bal_policy) and enable ALUA
(alua_enabled).
Perform these settings to match the ETERNUS DX model and depending on whether the OS supports ALUA.
8.2.1

Setting the I/O Load Balance Policy (load_bal_policy)

Set the I/O load balance policy to match the ETERNUS DX model being used as shown below. The policy set-
ting is required for all LUNs in the ETERNUS DX.

Example procedure of I/O load balance policy setting
Setting the I/O load balance policy to "round_robin"
-
# scsimgr save_attr -D /dev/rdisk/disk25 -a load_bal_policy=round_robin
Execute this "load_bal_policy" setting command for all LUNs in the ETERNUS DX.
If the I/O load balance policy is "preferred_path", a priority path must be set. Set the path that is used
when the I/O load is balanced as the priority path.
Example procedure priority path setting
Specify the hardware path of the "Lunpath" that is to be the priority path.
-
# scsimgr save_attr -D /dev/rdisk/disk25 -a preferred_path=64000/0x0/0x0.0x0.0x4
000000000000000
Lunpath hardware paths can be checked using the "ioscan -m lun" and "scsimgr lun_map" commands.
