Importing cloned disks with tags
In this example, cloned disks (BCV devices) from an EMC Symmetrix DMX array
will be imported. The primary (non-cloned) disks, mydg01, mydg02 and mydg03, are
already imported, and the cloned disks with the tag t1 are to be imported.
# vxdisk -o alldgs list
DEVICE TYPE DISK GROUP STATUS
EMC0_4 auto:cdsdisk mydg01 mydg online
EMC0_6 auto:cdsdisk mydg02 mydg online
EMC0_8 auto:cdsdisk - (mydg) online udid_mismatch
EMC0_15 auto:cdsdisk - (mydg) online udid_mismatch
EMC0_18 auto:cdsdisk mydg03 mydg online
EMC0_24 auto:cdsdisk - (mydg) online udid_mismatch
The disks are tagged as follows:
# vxdisk listtag
DEVICE NAME VALUE
EMC0_4 t2 v2
EMC0_4 t1 v1
EMC0_6 t2 v2
EMC0_8 t1 v1
EMC0_15 t2 v2
EMC0_18 t1 v1
EMC0_24 t1 v1
EMC0_24 t2 v2
To import the cloned disks that are tagged as t1, they must be assigned a new
disk group name, and their UDIDs must be updated:
# vxdg -n bcvdg -o useclonedev=on -o tag=t1 -o updateid import mydg
# vxdisk -o alldgs list
DEVICE TYPE DISK GROUP STATUS
EMC0_4 auto:cdsdisk mydg01 mydg online
EMC0_6 auto:cdsdisk mydg02 mydg online
EMC0_8 auto:cdsdisk mydg03 bcvdg online clone_disk
EMC0_15 auto:cdsdisk - (mydg) online udid_mismatch
EMC0_18 auto:cdsdisk mydg03 mydg online
EMC0_24 auto:cdsdisk mydg01 bcvdg online clone_disk
