No Downtime Seamless Migration
Why is the destination volume not mountable during migration?
By design, CMC has an Accidental Data Access Protection mechanism to prevent unintended data corruption to the migrated data. Issue While migration is in progress, the destination volume cannot be mounted. Explanation This behavior is by design. CMC has a Accidental Data Access Protection mechanism to prevent unintended data corruption to the migrated data. During different phases of the migration process, CMC ensures that OS or application only have access to the correct copy of

Can Cirrus Migrate Cloud migrate containers?
Can Cirrus Migrate Cloud migrate containers? Cirrus Migrate Cloud (CMC)'s block-level storage migration can migrate any block devices on the server, including the boot volume. Therefore, while it does not migrate on a per-container basis, any containers and container volumes within the selected migration volumes will be migrated.
My migration session's status is "IN ERROR". What does that mean?
This article describes the common causes of migration errors and appropriate actions to be taken to resolve them. Migration Status "IN ERROR" When one or more volumes within a migration session encounter migration error, the migration session will become in error. Once a migration volume is in error, synchronization will be suspended after appropriate retry attempts. However, unlike a "migration failed" status, synchronization progress is preserved when a session is in error. O

How to establish host-to-host (H2H) network connections for remote migration?
How to establish host-to-host (H2H) network connections for remote migration? What is H2H Connection Host-to-Host (H2H) connections are optimized one-way TCP-based network connections that cirrus-migrate-cloud uses to facilitate remote-migration, which features always-on compression and encryption. By design, NO PRODUCTION DATA / I/O leaves the production network during the entire migration phase. As a result, direct connectivity between the source and destination host is requ
How to open up TCP ports in Linux/Windows OS-level Firewall?
if this host is designated as a receiver for establishing an H2H connection, the following system commands can be used to open up port 4996 for Inbound connection. RHEL-based Linux 7+ (Redhat, CentOS, Amazon Linux, Rocky Linux, Fedora)
How to take an X-Ray for Cirrus Support?
When a support ticket is opened with Cirrus Data Cloud Support Team, an X-Ray is often requested. An X-Ray is a support package that consists of detailed application logs and runtime data such as migration session status. Taking X-Ray from Cirrus Data Cloud X-Ray can be taken via Cirrus Data Cloud UI. To take an X-Ray, go to your host's details page, click on the hamburger menu on the top right corner, and select **Download

How to Unmask a Disk that is Masked by CMC Migration
During the various phases of a CMC migration process, the source and/or destination disk is masked to prevent accidental usage by the user. Further, any snapshot taken by the destination storage (when a CMC Integration is invoked) is also masked unless there is an additional Action defined to unmake the destination prior to calling the snapshot (and in that case, yet another Action should be defined following the Snapshot action to mask the destination again). All these necessitates the availa
How to set up a migration schedule?
When creating a migration session, a migration schedule can optionally be set up to: Only start migration after a specific absolute time Use different **iQoS Impact Level **at different time of the week. Suspend migration activities at different time of the week. If migration schedule is NOT enabled for a migration session, the session will be migrating 24/7 at the selected iQoS Level.
