组网及说明
我以 Legacy T-Class 3PAR 在线迁移到 V-Class 组网案例
配置步骤
#3PAR Peer Motion Procedure
我们用TClass 和 VClass 之间做数据迁移。 其中T_Class InformOS : 3.1.3 MU1 V-Class 3.2.2 MU4
两套存储端口设置为以下：
T-Class Ports
2:2:2 PM Host Port
2:5:1 host port
2:3:2 RCFC port
2:6:1 RCIP Port
3:2:2 PM Host Port
3:5:1 host port
3:3:2 RCFC port
3:6:1 RCIP Port
V-Class Ports

You are about to enable a new zoning configuration.
This action will replace the old zoning configuration with the
current configuration selected. If the update includes changes
to one or more traffic isolation zones, the update may result in
localized disruption to traffic on ports associated with
the traffic isolation zone changes

在 V-Class 取两个 free port （Ready） 设置为 peer port 我们这里那 0：3：4 和 1:3:4 两个端口。
V400 cli% controlport offline 0:3:4

select q=quit y=yes n=no: y
V400 cli% controlport offline 1:3:4

V400 cli% controlport config peer -ct point 1:3:4
Are you sure you want to run controlport config peer -ct point on port 1:3:4?

特别注意一点这时设置为 Peer Port之后 端口 WWPN 发生变化了。
我们接下来把 T-Class 的 2:2:2 和 3:2:2 设置为 host port 这两个端口分别和 V-Class 的0：3：4 和 1：3：4 划了ZONE的。
T400 cli% controlport offline 2:2:2
Are you sure you want to run controlport offline on port 2:2:2?
select q=quit y=yes n=no: y
T400 cli% controlport offline 3:2:2
Are you sure you want to run controlport offline on port 3:2:2?
select q=quit y=yes n=no: y
T400 cli%
这里要强调注意一点 ： 如果将端口设置为 Peer port 之后这个端口的 WWPN 会发生改变
T400 cli% showport

2:2:2 initiator offline 2FF70202AC00172E 22220202AC00172E free FC - - -
>>>>>> 原来的WWPN是 22220002AC00172E 设置为 peer port 后就会变为 22220202AC00172E
3:2:2 initiator offline 2FF70202AC00172E 23220202AC00172E free FC - - -

我们将 T-Class 的端口类型改为 Host Port 后 WWPN就变回 00 而不是 02 ，这时要重新调整ZONE。
T400 cli% showport
N:S:P Mode State ----Node_WWN---- -Port_WWN/HW_Addr- Type Protocol Label Partner FailoverState
2:2:2 target ready 2FF70002AC00172E 22220002AC00172E free FC - 3:2:2 none

重新调整 ZONE

这样在 V-Class 上就可以通过 showtarget 看到 T-Class，并且端口类型也变为 Peer Port
V400 cli% showtarget

1:3:4 initiator ready 2FF70202AC001BAE 21340202AC001BAE peer FC - - -
我们在 T-Class 上看看端口类型，已经变为 Host Port
T400 cli% showtarget

这时我们是有VV映射给 T-Class 通过主机端口 2：5：1， 3：5：1

我们回到 V-Class 看 T-Class 都有哪些 LUN、

下面我在配置Peer Motion之前，先确认配置的 Peer Port并没有VV 映射过来。 （0：3：4，1：3：4没有VV映射）
V400 cli% showvlun -host BL460G6

接下来我们需要将 Peer Port 创建主机 （在错误一侧存储配置，端口显示"---"状态）
V400 cli% createhost pmhost 20340202AC001BAE 21340202AC001BAE
Setting default host persona 2 (Generic-ALUA)
V400 cli%
V400 cli% showhost

V400 cli%
上面做法是错误的，原来不应该在目标端存储 （V-Class）创建主机，而应该是在源端存储 T-Class 创建主机。
T400 cli% createhost pmhost 21340202AC001BAE 20340202AC001BAE

T400 cli%
然后我们需要在 T-Class 源端存储将需要同步的 VV 映射给新创建的主机 pmhost
T400 cli% createvlun pmvv1 auto pmhost
Warning: Virtual volume pmvv1 is already exported.
Unless this volume is being exported to a clustered environment, creation of
multiple exports could lead to data corruption. To avoid accidental creation
of multiple exports, consider setting the virtual volume policy to restrict
export to a single host.
Do you still wish to continue with the export?

我们这时可以在客户端主机上创建 LVM
[root@rhel7 ~]# multipath -ll

这时我们在目标端存储通过 showtarget -lun all 可以看到源端存储映射过来的 VV，可以看到卷类型，卷大小。
V400 cli% showtarget -lun all

V400 cli%
但这时我们看到 State 状态还是为空，这样在目标端存储 admitvv 就会提示找不到源存储 VV WWN
V400 cli% admitvv pmvv1:50002AC00887172E:50202AC00887172E
Remote VV WWN 50002AC00887172E does not exist

V400 cli%
这个时候我们必须要强制扫描一次，通过 showtarget -lun all 看到对端VV的状态为 discovered 才正确
V400 cli% showtarget -force -rescan
V400 cli% showtarget -lun all

我们这个时候才再次提交这个卷，提交成功
V400 cli% admitvv pmvv1:50002AC00887172E

我们在目标端存储查看该 VV 状态为 peer类型

接下来我们在目标端存储将该 VV 映射给服务器
V400 cli% createvlun pmvv1 auto BL460G6
V400 cli% showvlun -host BL460G6

0 pmvv1 BL460G6 10000000C9902674 1:2:2 host active 2
-------------------------------------------------------------------
最后我们要执行 importvv 动作就是将 T-Class 上的 pmvv1 迁移到 V-Class 的 pmvv1, 在迁移同时我要对这个VV对应的 LVM 持续写入 20G 随机数据，看在写入数据同时做数据迁移有什么变化。
dd if=/dev/urandom of=/pmvv/pmvv.urandom bs=1M count=20000
[root@rhel7 ~]# dd if=/dev/urandom of=/pmvv/pmvv.urandom bs=1M count=20000 &

[root@rhel7 ~]#
再执行importvv 时要求再次提交，因为这时的State状态为discovered, 应该正确为 admitted.
V400 cli% importvv -tpvv FC_r5 pmvv1
