InfoScale 7.1 FSS mirroring
I am trying to use FSS to mirror SAN based disks to local disk, the steps I have gone through to export the disks work fine as listed below
[root@server101 ~]# vxdisk -e -o alldgs list
DEVICE TYPE DISK GROUP STATUS OS_NATIVE_NAME ATTR

but when I try to mirror a 1GB volume I get the following errors

any thoughts would be of great help
Hi,
Why are you doing this? FFS is supposed to be for mirroring between hosts that don't have access to shared disks. If you want to mirror your internal disks to external, you can just make a mirror.
Please share more information.
