[PATCH 02/18] multipath-tools: Remove ONTAP IBM Nseries from hwtable

[Xose Vazquez Perez]

Originally from Martin George <marting@netapp.com>

He wrote:
"Even earlier, the NetApp IBM Nseries product line never used a
VID/PID of "IBM" & "Nseries" respectively. Instead, it always
used the same VID/PID of "NETAPP" & "LUN" itself, similar to the
ONTAP product line. So this piece of code was redundant from the
beginning itself."

[PATCH 16/18] multipath-tools: Use ALUA for HP 3PAR

[Xose Vazquez Perez]

Original patch from Hannes Reinecke <hare@suse.de>:

 		.vendor        = "3PARdata",
 		.product       = "VV",
 		.features      = DEFAULT_FEATURES,
-		.hwhandler     = DEFAULT_HWHANDLER,

+		.no_path_retry = 18,
+		.checker_name  = TUR,
+		.prio_name     = PRIO_ALUA,
 		.prio_args     = NULL,

Sebastian was not convinced with this change, full thread: https://marc.info/?t=146175638600002
But there is no automatic way to change .pgpolicy from MULTIBUS to GROUP_BY_PRIO.
So we should stick to latest manufacturer's recommendations:

"With 3PAR OS 3.1.3 or later, Hewlett Packard Enterprise recommends host persona
2 (ALUA). Advantages of Host Persona 2 (ALUA):
o A single VV migration can be performed by using 3PAR Peer Motion if the
  source and destination 3PAR StoreServ Storage array uses host persona 2
  (required by the 3PAR OS).
o Host persona 2 is required for Storage Federation (required by the 3PAR OS).

*3PAR plans to support additional features in later HPE 3PAR OS releases only at
  Generic-ALUA Persona 2

Persona_Number Persona_Name   Host_Operating_System       Additional_Capabilities
============== ============== ==========================  =======================
1              Generic        Linux, Windows and Solaris  UARepLun, SESLun
2              Generic-ALUA   Linux, Windows and Solaris  UARepLun, SESLun, ALUA
6              Generic-Legacy Linux, Windows and Solaris  None

o UARepLun -  Notifies the host of newly exported VLUNs and should trigger a LUN
              discovery request on the host, making the VLUN automatically
              available on format.
o SESLun   -  Enables iSCSI Enclosure Services (SES) LUN ID 254 for Host Explorer
              agent support.
o ALUA     -  Enables the Asymmetric Logical Unit Access (ALUA) command and
              asymmetric state change unit attention when path counts change
              due to adding or removing ports in the host's definition."

So 'retain_attached_hw_handler' suggested by Hannes doesn't work?

No. It's related to hardware_handler, "alua" in this case.

So how does the output of 'multipath -ll' looks like for persona 1 and 2
with and without 'retain_attached_hw_handler'?

retain_attached_hw_handler is innocuous.
The paths grouping policy is controlled by the "path_grouping_policy" keyword,
multibus vs. group_by_prio. See man page.


Persona 1 and 2 basically is the same, but:

Persona 1:	path_grouping_policy = multibus
		failback = manual
		prio = const

Persona 2:	path_grouping_policy = group_by_prio
		failback = immediate
		prio = alua				(this is irrelevant, alua-prio is autodetected)
		hardware_handler= "1 alua"		(this is irrelevant, all hardware handlers are autodetected)

With 3PAR-OS 3.1.3, or later, you should use "Persona 2"

multibus should equal

path_grouping_policy = group_by_prio
prio = const

The above change plus

retain_attached_hw_handler = yes
detect_prio = yes

should work with persona 1 and 2.

3PAR arrays are Symmetric Active/Active and with ALUA support.


- With Persona 1/Generic(UARepLun, SESLun), only one mode is supported:

o Symmetric Active/Active
        {
                .vendor        = "3PARdata",
                .product       = "VV",
                .pgpolicy      = MULTIBUS,
                .no_path_retry = 18,
        },


- With Persona 2/Generic-ALUA(UARepLun, SESLun, ALUA), both of them are supported:

o Symmetric Active/Active
        {
                .vendor        = "3PARdata",
                .product       = "VV",
                .pgpolicy      = MULTIBUS,
                .no_path_retry = 18,
        },

o Symmetric Active/Active + ALUA
        {
                .vendor        = "3PARdata",
                .product       = "VV",
                .pgpolicy      = GROUP_BY_PRIO,
                .pgfailback    = -FAILBACK_IMMEDIATE,
                .hwhandler     = "1 alua",
                .prio_name     = PRIO_ALUA,
                .no_path_retry = 18,
        },


Thera are also others Symmetric Active/Active arrays with support of ALUA.
At least, EMC/SYMMETRIX and IBM/2810XIV.
