After adding the new disks to the diskgroup. Then it immediately triggers a rebalancing operation that can be monitored through the v$asm_operation view.
--> A question like while rebalancing is going node got hanged got alert error like ASM MAXIMUM PROCESS GOT EXCEED so no operation were allowed to the node, so we rebooted the node after rebooted node came in to normal state and able to do all operation normally..but my question is that rebalance is completed succesfully or not?
SQL> select group_number, operation, est_minutes from v$asm_operation; GROUP_NUMBER OPERA EST_MINUTES ------------ ----- ----------- 1 REBAL 4 Once completed the reblance operation it will disappear from the v$asm_operation view. SQL> select group_number, operation, est_minutes from v$asm_operation; no rows selected
