InfoScale 7.1 FSS mirroring

shad
Level 1

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
emc0_dd1 auto:cdsdisk ora_cfs_dg01 ora_cfs_dg online shared sds RAID+Mirr lun

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.
