NBU fails to delete disk pool
I executed a command on NBU ( V 6.5 + Linux platform )
nbdevquery -listdp -stype XXX And it gave the output V6.5 DefaultDP_1 1 268435456.00 268435456.00 1 98 80 XXX
Now after some time I tried to delete the diskpool 'DefaultDP_1'
nbdevconfig -deletedp -stype XXX -dp DefaultDP_1 -M YYY which gave the output 'DSM was unable to find the following disk pool: DefaultDP_1(XXX)@YYY\n', 'failed to delete disk pool, invalid command parameter\n'], returnCode: 20'
I am surprised to see such output that how DSM could not found diskpool that it has reported a few minutes ago.
How can I analyse such cases by seeing NBU logs ?
Is this a normal scenerio which can happen from time to time ?
I have encountered such type of problems that NBU does not able to find policy etc. which are already craeetd on it. Now , is this a kind of database error ?
