OceanStor 5800 V3 After creating LUN, the customer can't identify the real name of LUN

Publication Date:  2015-07-05 Views:  152 Downloads:  0
Issue Description

Customers runs CLI command create Lun to create the specified LUN named "DB pool Db_pool_mis0103_08 08". To run the query command after created, it is found that the real name of LUN is inconsistent with the named. The LUN name is actually "db_pool_mis0103_080000":

Alarm Information

LUN related information as follows:

Handling Process
The command create lun which customer used is implemented for creating a batch of multiple LUNs. To modify the command parameter create lun, instead of creating a single LUN, with the parameter lun_id instead of lun_id_list:
create lun name=db_pool1_mis0103_08 pool_id=7 capacity=300GB lun_id=208 allocation_policy=extreme_performance owner_controller=0A relocation_policy=automatic
Root Cause
The command create lun can be implemented for creating a single LUN or a batch of multiple LUNs by the different parameters. When create a batch of multiple LUNs, in order to provide convenience for customer, the system names the batch of LUNs with the automatic number, which is named with four digits suffix (it’s the beginning of 0000). For example, it’s named LUN, then the batch of LUNs named LUN0000, LUN0001, etc.
Solution
To modify the command parameter create lun, instead of creating a single LUN, with the parameter lun_id instead of lun_id_list:
create lun name=db_pool1_mis0103_08 pool_id=7 capacity=300GB lun_id=208 allocation_policy=extreme_performance owner_controller=0A relocation_policy=automatic
Suggestions
This issue is mostly due to that there is no correct understanding of the functional characteristics in particular or more complex application scenarios. It causes the results that the expected results are not consistent with real. The suggestion for processing the similar problems is to have identification with whether the use of product features is appropriate by the product manual.
