Hi Mladen!,
Thank you for your input. I am using UDEV and not ASMLIB to manage these
devices. I had an SA re-initialize the device and also clean it up using DD.
Once it was done, the MOUNT and HEADER statuses changed to CLOSED and CANDIDATE
respectively as shown below:
OS disk Space Space
Disk
Mount Header Mode Disk Size Total Free
ASM Disk Failgroup Vote
Ins# Grp# Disk# Status Status Status State (MB) (MB) (MB)

I tried to add the disk but got the same result (this syntax was suggested by
the Oracle Engineer):
SQL> ALTER DISKGROUP GRID ADD DISK '/dev/oracleasm/grid/asmgrid01' size 2048M
rebalance power 11
*
ERROR at line 1:
ORA-15032: not all alterations performed
ORA-15410: Disks in disk group GRID do not have equal size.
The following command shows that these devices have the same size:
+ASM1> blockdev -v --getsize64 /dev/oracleasm/grid/asmgrid01
/dev/oracleasm/grid/asmgrid02 /dev/oracleasm/grid/asmgrid03
get size in bytes: 21485574144
get size in bytes: 21485574144
get size in bytes: 21485574144
The Oracle SR is now back to Work In Progress status.
Thank you,
Amir

Hi Amir!
Please delete device using oracleasm and then clean up the device using dd. I
don't like oracleasm because it writes header and therefore changes the device
size. I prefer SCSI driver setup through udev rules, like described here:
https://oracle-base.com/articles/linux/udev-scsi-rules-configuration-in-oracle-linux

This is confusing because all of the disks allocated to the grid DG are of the
same size. After I added '/dev/oracleasm/grid/asmgrid01' to TEMPDG, the
GV$ASM_DISK.TOTAL_MB shown the size the same as for
'/dev/oracleasm/grid/asmgrid02' and '/dev/oracleasm/grid/asmgrid03'
Thanks,
Amir
