I am trying to create a workflow that can create num of volumes and choose the names by the icremental naming.
I already have nati_vol_1
I want to execute the workflow to cretae nati_vol_4,5,6 and 7.
I already configured the raw loop to Number of times and the volume name to incremental naming.
I search by aggregate and volume name prefix.
volume name prefix: $volumename
value for name if no volume matches the above criteria:
Incerement by 1
(Its allow me to create the vol from 1 to 4 in case that 1-3 doesn't exist...)
the problem is that the workflow can create just 4 and 5.
the validation of the execution plan failed becase he plan to create nati_vol_4, nati_vol_5 and than nati_vol_5 again (is it because nati_vol_5 doesn't exist ?!)
Someone know how to help me ?
The question is not clear.
Can you please elaborate on this part:
"the problem is that the workflow can create just 4 and 5.
the validation of the execution plan failed becase he plan to create nati_vol_4, nati_vol_5 and than nati_vol_5 again (is it because nati_vol_5 doesn't exist ?!)"
you can see how I have configured the incremental volume name
the second picture show the execution failed when I try to repet the creation 4 times. (I already have vol__orange_sas_11 in the controller and I wnat to creae 12,13,14,15)
is it better explaination ?
I could not access the jpegs. Somehow the mail with the jpegs are not appearing
in the web page.
Meanwhile I am preparing a simple workflow to demonstrate the same.
I will hopefully be able to send it tomorrow.
This is why I think it is not incrementing.
When searching for volumes, it is always searching for the highest number volume.
Let us say the search finds vol__orange_sas_11. It is incremented by 1 in the first iteration of the for loop. So it becomes
In the next iteration again it searches vol__orange_sas_11, because vol__orange_sas_12 will not be there in the
DB unless your command which you are using to create the volume has reservation enabled.
So it again tries to create vol__orange_sas_11 and fails.
In order to solve this you can increment by =1+index ( this is the for loop’s index).
work greak !
I have another question in this issue.
The search find the vol just if I specified the full name of the volume. (Include the number).
If I search for "vol_vm_orange_sas_" its not find the volume vol_vm_orange_sas_11 and Its take the value for volume that not match the criteria.
In addition, when I search vol "vol_vm_orange_sas_10" the flow for execution plan to create 11,12,13 although volume name "vol_vm_orange_sas_11" already exist (I thouth its search the highest number)
Good to hear that it works.
This is what I understand:
1. The DB already has vol_vm_orange_sas_11.
2. This is the volume name which has the highest number in the suffix.
3. If you search for vol_vm_orange_sas_ then it is not finding vol_vm_orange_sas_11.
Actually this is because of the SQL query.
The SQL query is not correct.
You need to find an SQL query which can find vol_vm_orange_sas_11 when you enter vol_vm_orange_sas_.
You can sort by descending (DSC). If you use DSC it will work from vol_vm_orange_sas_0 to vol_vm_orange_sas_9.
In order to make it work beyond 10, the SQL query will be little more complicated.
