Detached volumes remain associated with their replication sets but are not updated with replication data or with replication control information. NOTE: It is recommended that the vdisk that you are moving contains only secondary volumes and their snap pools. You are allowed to move other volumes along with secondary volumes and their snap pools, but be sure that you are doing so intentionally. NOTE: If you intend to move a vdisk's drive enclosure and you want to allow I/O to continue to the other enclosures, it is best if it is at the end of the chain of connected enclosures. If the enclosure is in the middle of the chain, the enclosures must be cabled with no single point of failure, so that removing the enclosure does not prevent communication between other enclosures.

In the main panel, click Detach Replication Volume. A message indicates whether the task succeeded or failed. When a volume is detached its status is shown as Detached. Stopping a vdisk Stopping a vdisk is part of the process for moving a secondary volume into a secondary system. The process to move a secondary volume is: 1. In the system where the secondary volume resides: a. Detach the secondary volume. For details see Detaching a secondary volume on page 117. b. If the secondary volume's vdisk contains other secondary volumes, detach those volumes. c. Stop the secondary volume's vdisk. d. If the secondary volumes' snap pools are in other vdisks, stop those vdisks. e. Move the vdisks into the secondary system. 2. In the secondary system: a. Start the snap pools' vdisks. For details see Starting a vdisk on page 119. b. Start the secondary volumes' vdisks. c. Reattach the secondary volumes. For details see Reattaching a secondary volume on page 119. Before stopping a vdisk, ensure that all secondary volumes that it contains are detached. When a vdisk is stopped: • The volumes in the vdisk become inaccessible to hosts. • Its cached data is flushed to disk. • Removing its disks will not cause the system to report errors or to attempt reconstruction. NOTE: You cannot stop a vdisk that contains a primary volume. 118 Using Remote Snap to replicate volumes

Using Remote Snap to replicate volumes

Stop the secondary volume’s vdisk. For details see

Stopping a vdisk

on page 118.

If the secondary volumes’ snap pools are in other vdisks, stop those vdisks.

Move the vdisks into the secondary system.

In the secondary system:

Start the snap pools’ vdisks. For details see

Starting a vdisk

on page119.

Start the secondary volumes’ vdisks.

Reattach the secondary volumes. For details see

Reattaching a secondary volume

on page 119.

Detached volumes remain associated with their replication sets but are not updated with replication data

or with replication control information.

NOTE:

It is recommended that the vdisk that you are moving contains only secondary volumes and their

snap pools. You are allowed to move other volumes along with secondary volumes and their snap pools,

but be sure that you are doing so intentionally.

NOTE:

If you intend to move a vdisk’s drive enclosure and you want to allow I/O to continue to the other

enclosures, it is best if it is at the end of the chain of connected enclosures. If the enclosure is in the middle

of the chain, the enclosures must be cabled with no single point of failure, so that removing the enclosure

does not prevent communication between other enclosures.

To detach a secondary volume

In the Configuration View panel, right-click the secondary volume and select

Provisioning > Detach

Replication Volume

In the main panel, click

Detach Replication Volume

. A message indicates whether the task succeeded

or failed. When a volume is detached its status is shown as Detached.

Stopping a vdisk

Stopping a vdisk is part of the process for moving a secondary volume into a secondary system. The

process to move a secondary volume is:

In the system where the secondary volume resides:

Detach the secondary volume. For details see

Detaching a secondary volume

on page117.

If the secondary volume’s vdisk contains other secondary volumes, detach those volumes.

Stop the secondary volume’s vdisk.

If the secondary volumes’ snap pools are in other vdisks, stop those vdisks.

Move the vdisks into the secondary system.

In the secondary system:

Start the snap pools’ vdisks. For details see

Starting a vdisk

on page119.

Start the secondary volumes’ vdisks.

Reattach the secondary volumes. For details see

Reattaching a secondary volume

on page 119.

Before stopping a vdisk, ensure that all secondary volumes that it contains are detached. When a vdisk is

stopped:

•

The volumes in the vdisk become inaccessible to hosts.

•

Its cached data is flushed to disk.

•

Removing its disks will not cause the system to report errors or to attempt reconstruction.

NOTE:

You cannot stop a vdisk that contains a primary volume.
