A U2000 earlier than V100R006C02 can properly manage cross-connect capacity subracks of the OSN 8800. After it is upgraded to the U2000 V100R006C02 or a later version, an alarm is generated indicating insufficient number of license items for subracks with a certain type of cross-connect capacity.

1.2 [Problem Description]
On the U2000 V100R006C02 and later versions, the license control mode for cross-connect capacity subracks of the OSN 8800 is changed from the common deduction mode to stepped deduction mode based on the sales mode of cross-connect capacity subracks. As a result, when either of the trigger conditions is met, an alarm indicating insufficient number of license items for cross-connect capacity subracks is generated.
Sales mode of cross-connect capacity subracks: If a customer sets the cross-connect capacity to 1.28 TB for an OTN subrack, the customer needs to purchase a 360 GB, a 360 GB-720 GB, and a 720 GB-1.28 TB license item respectively.
Common deduction mode: If the cross-connect capacity of a subrack is set to 1.28 TB, the U2000 deducts only a 720 GB-1.28 TB license item without deducting any 360 GB and 360 GB-720 GB license items.
Stepped deduction mode: If the cross-connect capacity of a subrack is set to 1.28 TB, the U2000 deducts a 360 GB, a 360 GB-720 GB, and a 720 GB-1.28 TB license item respectively.
Trigger conditions:
A U2000 earlier than V100R006C02 uses the common license deduction mode. If either of the following scenarios occurs, an alarm will be generated indicating insufficient number of license items:
Scenario 1: A customer only purchases a 720 GB-1.28 TB license item and sets the cross-connect capacity of a subrack to 1.28 TB. The U2000 earlier than V100R006C02 can properly manage the subrack NE. After being upgraded to the U2000 V100R006C02 or a later version, the U2000 uses the stepped license deduction mode. As a result, the U2000 cannot manage the subrack NE due to the lack of a 360 GB and a 360 GB-720 GB license item.
Scenario 2: A customer purchases a 360 GB, a 360 GB-720 GB, and a 720 GB-1.28 TB license item respectively. The U2000 earlier than V100R006C02 uses the common license deduction mode and allows the customer to set three types of cross-connect capacity, 360 GB, 720 GB, and 1.28 TB, for an OTN subrack. After being upgraded to the U2000 V100R006C02 or a later version, the U2000 uses the stepped license deduction mode and allows the customer to set only 1.28 TB cross-connect capacity for the OTN subrack. As a result, the U2000 cannot manage the subracks with 320 GB and 720 GB cross-connect capacity due to the lack of the 360 GB and 360 GB-720 GB license items.

Symptom:
The following two figures show the changes of license item consumption after a U2000 is upgraded to the U2000 V100R006C02 or a later version.

Figure 1-1 Before the upgrade:

Figure 1-2 After the upgrade:

Identification method:

  • Method 1:

Based on the actual number of consumed license items on the U2000 earlier than V100R006C02, manually calculate that after the upgrade and compare it with the number of purchased license items.
The calculation formula is as follows:
Number of consumed 360 GB license items (after the upgrade) = Actual number of consumed 360 GB license items (before the upgrade) + Actual number of consumed 720 GB license items (before the upgrade) + Actual number of consumed 1.28 TB license items (before the upgrade) + Actual number of consumed 2.56 TB license items (before the upgrade)
Use Figure 1-1 and Figure 1-2 as an example.
Number of consumed 360 GB license items (after the upgrade: 38) = Actual number of 360 GB license items (before the upgrade: 1) + Actual number of 720 GB license items (before the upgrade: 5) + Actual number of 1.28 TB license items (before the upgrade: 4) + Actual number of 2.56 TB license items (before the upgrade: 28)
In the same way, use the following formulas to calculate the number of consumed 360 GB-720 GB, 720 GB-1.28 TB, and 1.28 TB-2.56 TB license items after the upgrade:Number of consumed 360 GB-720 GB license items (after the upgrade) = Actual number of consumed 720 GB license items (before the upgrade) + Actual number of consumed 1.28 TB license items (before the upgrade) + Actual number of consumed 2.56 TB license items (before the upgrade)

Number of consumed 720 GB-1.28 TB license items (after the upgrade) = Actual number of consumed 1.28 TB license items (before the upgrade) + Actual number of consumed 2.56 TB license items (before the upgrade)
Number of consumed 1.28 TB-2.56 TB license items (after the upgrade) = Actual number of consumed 2.56 TB license items (before the upgrade)

Compare the calculated number of license items with the number of license items purchased by the customer, and determine whether the license quantity meets post-upgrade requirements. If the number of consumed license items for subracks with a certain type of cross-connect capacity exceeds the number of purchased license items, rectification is required.

  • Method 2:

Before the upgrade, use the UEsay (V100R009C00SPC200 or later versions) to check the U2000. If the UEsay prompts that the number of licenses will be insufficient after the upgrade, rectification is required.

  • Method 3:

After the U2000 is upgraded, if the U2000 license information indicates insufficient number of subracks with a certain type of cross-connect capacity on the OSN 8800, rectification is required.
1.3 [Root Cause]
On the U2000 V100R006C02 and later versions, the license control mode for cross-connect capacity subracks of the OSN 8800 is changed from the common deduction mode to stepped deduction mode based on the sales mode of cross-connect capacity subracks. As a result, when either of the trigger conditions is met, an alarm indicating insufficient number of license items for cross-connect capacity subracks is generated.

1.4 [Impact and Risk]
On the U2000 V100R006C02 and later versions, if the number of license items is insufficient but the customer does not purchase required license items in time:


  • The U2000 reports alarms.
  • You cannot set cross-connect capacity for the OTN subracks that have insufficient number of license items.

1.5 [Measures and Solutions]

Preventive measures

Solutions
If your office encounters the problem and meets the trigger conditions, follow the rectification instructions to obtain required license items to resolve the insufficiency of cross-connect capacity subracks.

1.6 [Rectification Instructions]
The way of obtaining a license file by following the software license rectification process is the same as that of obtaining a license based on the contract. After an onsite engineer submits a batch license rectification application, the engineer obtains a new contract number and PO number. Then the engineer can activate and download the desired license file based on the contract number or PO number in the FlexNet Operations System (FNO).
