Description

The production host has two images of the diskgroup "prodg".

NOTES:

EMC BCV cloned images of EMC STD lun "emc1_0120" have been performed to "emc1_00dc" and "emc1_011e"

EMC BCV cloned images of EMC STD lun "emc1_0121" have been performed to "emc1_00dd" and "emc1_011f"

BCV group #1 contains "emc1_00dc" and "emc1_00dd"

BCV group #2 contains "emc1_011e" and "emc1_011f"

* All the EMC BCV images have been split with symmir.

Prior to importing the respective EMC BCV cloned images, set a memorable VxVM tag corresponding to the group of BCV luns
 

dopey# vxdisk settag bcv1 emc1_00dc emc1_00dd
dopey# vxdisk settag bcv2 emc1_011e emc1_011f

How to list the VxVM tag content

dopey# vxdisk listtag
DEVICE          NAME                            VALUE
emc1_00dc       bcv1                            -
emc1_00dd       bcv1                            -
emc1_011e       bcv2                            -
emc1_011f       bcv2                            -

How to import the EMC devices associated with VxVM tag "bcv"

* To use the "-o useclonedev=on and -o updateid" you will require the Storage Foundation Enterprise License.

dopey# vxdg -n bcv1_prodg -o useclonedev=on -o updateid -o tag=bcv1 import prodg

The above command imports EMC luns associated with tag "bcv1", in this instance "emc1_00dc" and "emc1_00dd"

dopey# vxdg -n bcv2_prodg -o useclonedev=on -o updateid -o tag=bcv2 import prodg

The above command imports EMC luns associated with tag "bcv2", in this instance "emc1_011e" and "emc1_011f"

Following the multple EMC BCV diskgroup imports, the "clone_disk" disk flag attribute will be populated against the corresponding EMC BCV luns.

Extended attribute content displayed when running "vxdisk -e list"

dopey# vxdisk -e -o alldgs list | grep prodg

* Extended attribute content highlighting hardware technology is available as of 5.0 MP3.

In this instance, EMC STD and EMC BCV luns can be easily identified.
