Steps to unpresent the EMC MirrorView SnapView (cloned) devices

1.]  Ensure all corresponding filesystems are unmounted.

2.] Deport the cloned diskgroup images, in this instance "asyncDG1_fd", "asyncDG2_fd" and "asyncDG3_fd"

# vxdg deport asyncDG1 asyncDG2 asyncDG3

3.] Confirm using "vxdg list" that all required diskgroup were deported

4.] Inform Volume Manager that the corresponding luns are to be removed, by running "vxdisk rm "

In this instance, the disk access names are "emc_clariion0_600_1", "emc_clariion0_601_1" and "emc_clariion0_602_1"

# vxdisk rm emc_clariion0_600_1 emc_clariion0_601_1 emc_clariion0_602_1

5.] Deactivate and remove the EMC MirrorView SnapView snapshot images using the EMC naviseccli utility.

How to deactivate and remove the EMC MirrorView SnapView snapshot with the name of "lun600_fd_snapshot"

Sample syntax

1.] Deactivate snapshot "lun600_fd_snapshot"

# /opt/Navisphere/bin/naviseccli -h 10.209.64.29 snapview -deactivatesnapshot -snapshotname lun600_fd_snapshot -o


2.] Remove snapshot "lun600_fd_snapshot" from EMC CLARiiON Storage group "vcssx065_066"

# /opt/Navisphere/bin/naviseccli -h 10.209.64.29 storagegroup -removesnapshot -gname vcssx065_066 -snapshotname lun600_fd_snapshot -o

3.] Remove the snapshot name "lun600_fd_snapshot"

# /opt/Navisphere/bin/naviseccli -h 10.209.64.29 snapview -rmsnapshot -snapshotname lun600_fd_snapshot -o

2.] Deactivate and remove snapshot "lun601_fd_snapshot"

# /opt/Navisphere/bin/naviseccli -h 10.209.64.29 snapview -deactivatesnapshot -snapshotname lun601_fd_snapshot -o

# /opt/Navisphere/bin/naviseccli -h 10.209.64.29 storagegroup -removesnapshot -gname vcssx065_066 -snapshotname lun601_fd_snapshot -o

# /opt/Navisphere/bin/naviseccli -h 10.209.64.29 snapview -rmsnapshot -snapshotname lun601_fd_snapshot -o

Once the EMC MirrorView SnapView snapshot's have been deactivated and removed, the related session needs to be stopped.
