2)如何查看注册信息

[root@jason1~]# powermt check_registration

KeyBXPV-CB4G-2FCK-QSIS-MC9M-JVJT

Product: PowerPath

Capabilities: All

[root@jason1~]#

[root@jason2~]# powermt check_registration

KeyBXPV-CB4G-2FCK-QSIS-MC9M-JVJT

Product: PowerPath

Capabilities: All

[root@jason2~]#

备注：两节点注册信息一致，当其中一节点重装系统之后，可以通过该命令在另一节点上查看注册信息获取key进行注册。

3)如何注册License

[root@jason2~]#emcpreg install

=========== EMC PowerPath Registration===========
Do you have a new registration key or keys to enter?[n] y
Enter the registration keys(s) for your product(s),
one per line, pressing Enter after each key.
After typing all keys, press Enter again.

Key(Enter if done): BXPV-CB4G-2FCK-QSIS-MC9M-JVJT
1 key(s) successfully added.
Key successfully installed.

Key(Enter if done):
1 key(s) successfully registered.

4)常见问题

mode模式unlic问题解决，如下情况。红色字体部分。

[root@jason2~]# powermt display dev=all

Pseudoname=emcpowera

CLARiiONID=CKM00103500808 [pacsserver-HA]

Logicaldevice ID=60060160C3102A0068A82245E5CADF11[LUN 0]

state=alive;policy=BasicFailover; priority=0; queued-IOs=0

Owner:default=SP B, current=SP B Arrayfailover mode: 1

==============================================================================

state=alive;policy=BasicFailover; priority=0; queued-IOs=0

Owner:default=SP B, current=SP B Arrayfailover mode: 1

==============================================================================

----------------Host --------------- - Stor - -- I/O Path - -- Stats ---

### HW Path I/O Paths Interf. Mode State Q-IOs Errors

==============================================================================

5 lpfc sdd SP A1 unlic alive 0 0

5 lpfc sdg SP B1 unlic alive 0 0

6 lpfc sdj SP B0 active alive 0 0

6 lpfc sdm SP A0 active alive 0 0

此问题是由于未注册lisence且mode未修改造成，通过注册lisence之后手动修改mode进行保存解决。如下：

[root@jason2~]#emcpreg install

Key(Enter if done): BXPV-CB4G-2FCK-QSIS-MC9M-JVJT
1 key(s) successfully added.
Key successfully installed.

Key(Enter if done):
1 key(s) successfully registered.

[root@jason2~]#powermt set policy=co dev=all

[root@jason2~]#powermt save

注册之后继续查看如下。

[root@jason2~]#powermt display dev=all

Pseudoname=emcpowera

CLARiiONID=CKM00103500808 [pacsserver-HA]

Logicaldevice ID=60060160C3102A0068A82245E5CADF11[LUN 0]
