License is a form of contract that stipulates the application scope and period of a specified product. After successfully obtaining the license, you can experience corresponding services stipulated on the license. Knowing the following points helps you solve license problems easily.
First, you need to license controlled functions of N8000.
[License Control Items]
License control items of N8500 are as follows:
- CIFS
- NFS
- FTP
- DST
- Snapshot
- File system Mirror
The dynamic storage tiering (DST) storage module and snapshot module are mutually exclusive. That is, the two features cannot be used in the same scenario. When the license is activated, it cannot generate both of the features.
Second, you need to know basic rules of license control.
[License Control rules]
- A feature is usable when the corresponding license is valid and the resource quantity is no less than the current cluster node quantity.
- If license is not purchased, the corresponding function is unavailable.
- When the license file becomes invalid or has expired, the feature is still available but cannot be extended.
- New nodes can be added only when the existing license resource quantity is greater than the cluster node quantity. If the existing license resource quantity is not greater than the cluster node quantity, new licenses must be purchased for new nodes.
- Version upgrade is supported. When the N8500 cluster is upgraded from V100R002 to V200R001, the original license file is still valid provided that no capacity expansion is required.
Third, you need to know how to apply for license.
[License Control rules]
- Obtain a license file.
- Obtain the contract number.
You can obtain the contract number from the packing list or LAC.
- Obtain the LAC.
Obtain the LAC from the license certificate.
- Obtain Equipment Serial Number (ESN).
Query the ESN from the component or its package.
Note:
If you apply for licenses of multiple devices, you need to match the ESN with LAC for each device.
- Fill in the license application form and send an email to license@huawei.com.
Huawei technical support personnel will handle your request as soon as receiving your email. Generally, you will be replied within one workday. Notice to check your mailbox.
- Check the license file.
After you obtain a license file, check whether its information is consistent with that in the contract. On Windows, open the license file using any text editor. On Linux, open the license file using vi. The following is an example:
Product=N8000
Feature=CIFS02
Esn="201006300000N8K0001"
Attrib="DEMO,2010-09-26,60,NULL,NULL,NULL"
Resource="LSTZCIFS01=12"
Comment="chengdu,SCDCHN106000,OR0000232-AEB7DD2F631E-SCDCHN10600000"
Sign=5910B813B7D5F50A93798B289F548886CF0BEE02CA490D6DE7B7243BF851
Verify that Feature and Resource stated in the license file are consistent with those in the contract. If any inconsistency is found, contact the technical support engineers.
- Verify and back up the license file.
After the license file has been successfully imported, verify that the license file is valid.
Note:
After the license file has been verified, copy the license file to a specified directory for backup. Once the license file is lost, you can obtain it according to ESN.
