Why does "sysconfig -r" show on some but not all the partner disks 0/0 Used?
Applies to
ONTAP 9
Answer
That is because filer does not access data on partner disks unless it does the takeover. In order to know the used size of the disk, RAID must read table of contents from that disk. Therefore, RAID usually reports only raw size of partner disks that results in showing used size for some, but not all partner disks.
Example of
sysconfig -r
output for this case (partial listing):RAID Disk Device HA SHELF BAY CHAN Used (MB/blks) Phys (MB/blks)
