Hi all,
OS: Solaris 11
DB: 11.2.0.3.5 (2 node rac)
While creating a new db on a Solaris 11 env, via dbca, the following stack error appeared to me:
ORA-19624: operation failed, retry possible
ORA-19870: error while restoring backup piece path[...]
ORA-19504: failed to create file "+MYDG"
ORA-00372: file cannot be modified at this time
ORA-15196: invalid ASM block header [kfc.c:19572] [1] [257] [0 != 821602346]
ORA-15081: failed to submit an I/O operation to a disk
ORA-15066: offlining disk "dsk_0001" in group "MYDG" may result in data loss
ORA-06512: at SYS.X$DBMS_BACKUP_RESTORE, line5827
The dbca (ran as oracle user) aborts at 15%.
There are a lot of errors in this stack, and i'm not pretty sure which error is the main cause of this issue, but I think it's the "ORA-15081: failed to submit an I/O operation to a disk" that is the bad guy here. I did some researches and found that some possible sollutions:
1) One said that this error might be caused by bad permissions on the raw devices used in the "MYDG" diskgroup (i'm using 6 devices with external redundancy), but my devices are all with the grid:asmadmin and 660 permissions
2) Another said that this might be a problem with the owner:group of the oracle binaries. In ny installation the oracle binaries ($ORACLE_HOME/bin) are with the oracle:oinstall. I thougth of addind the asmadmin group to the oracle user, but i'm not sure what are the implications of this change. What do you thing?
What am I doing wrong and how can i solve it?
Thanks in advance for your pacience and attention.
