Failback is not supported for replication policies that exclude directories. Discuss specific issues with EMC experts. On a cluster, create a replication policy for each directory that you want to migrate. When a replication job is completed, SyncIQ deletes the previous source-cluster snapshot and retains the most recent snapshot until the next job is run. If you want to run the disabled policy again, you must reset the replication policy. The following wildcard characters are accepted: For example, If you cannot resolve the issue that caused the error, you can reset the replication policy. For instructions, see Gathering cluster logs on page 26. EMC offerings in backup and recovery, enterprise content management, unified storage, big data, enterprise storage, data federation, archiving, security, and deduplication help customers move to and build IT trust in their next generation of information management and enable them to offer IT-as-a-Service as part of their journey to cloud computing. If you break the association of a policy, the policy is disabled on the source cluster and you cannot run the policy. top. The target directory is an empty SmartLock directory. drwxr-x— 4 root wheel 50 May 10 2014 node001 You can calculate your RPO and RTO for a disaster recovery with replication policies. The POSIX timestamp of when the item was last changed. Determines whether snapshots generated for the replication policy on the source cluster are deleted when the next replication policy is run. The target directory on the target cluster. If a cluster is rendered unusable, you can fail over to another Isilon cluster, enabling clients to access their data on the other cluster. You can create replication policies that determine when data is replicated with SyncIQ. *, If changelists are enabled for a policy, SyncIQ does not automatically delete the repstate files generated by the policy; if changelists are not enabled for a policy, SyncIQ automatically deletes the repstate files after the corresponding replication jobs complete. If multiple subreports are created for a job, SyncIQ combines the information from the subreports into a single report. Breaking a source and target cluster association causes SyncIQ to perform a full replication the next time the policy is run. Learn how your comment data is processed. For example, you cannot configure a replication policy to run every hour starting at 7:00 PM and ending at 1:00 AM. Configuring file-criteria statements can cause the associated jobs to run slowly. Administrator action This message is informational. You can modify the maximum number of workers generated per node to control the amount of resources that a replication job is allowed to consume. You can configure file-matching criteria statements during the replication-policy creation process. SyncIQ generates replication jobs according to replication policies. You can create two types of replication policies: synchronization policies and copy policies. When i run the command on a single node i get an output with no problem but when i try to add isi_for_array to check the cluster i get an invalid output shown below. The path, relative to the root path, of the file or directory that was modified or removed. Once a policy is deleted, SyncIQ no longer creates replication jobs for the policy. Snapshots generated by SyncIQ can also be used for archival purposes on the target cluster. If necessary, modify the policy settings. To migrate data that clients have modified on the secondary cluster, you must fail back to the primary cluster. /ifs/data/media from replication, and For example, the description might explain the purpose or function of the policy. When the client connects to the secondary cluster, all files that were deleted on the primary cluster will be available to the client. Gathering cluster logs. When a replication job runs, files from a directory on the source cluster are replicated to a directory on the target cluster; these directories are known as source and target directories. Because autocommit information is not transferred to the target cluster, files that were scheduled to be committed to a WORM state on the source cluster will not be scheduled to be committed at the same time on the target cluster. You can create a network traffic rule that limits the amount of network traffic that replication policies are allowed to generate during a specified time period. Let's talk about your consulting and IT service needs. Each file-criteria element contains a file attribute, a comparison operator, and a comparison value. You initiate the failover process on the secondary cluster. -t : Choose topic to browse. For example, the following command runs newPolicy: You can enable changelists only through the command-line interface (CLI). The next step in the process of creating a replication policy is configuring advanced policy settings. You can fail back data with any replication policy that meets all of the following criteria: The Recovery Point Objective (RPO) and the Recovery Time Objective (RTO) are measurements of the impacts that a disaster can have on business operations. Invalid argument: 12:00:01 SyncIQ generates snapshots to facilitate replication, failover, and failback between Isilon clusters. In addition to viewing replication reports, you can configure how long reports are retained on the cluster. You can recover SmartLock directories that you have replicated to a target cluster. Since the AuditAdmin role is “read only” I end up getting permissions denied. It is recommended that you specify file-criteria statements in a replication policy only if necessary. Searching for something, use the grep command to narrow it down. First step is to start an SSH session with Isilon. Use Live Chat for fast, direct access to EMC Customer Service Professionals to resolve your support questions. However, we recommend that you do not create more than 100 policies on a cluster. You must specify a target cluster and directory to replicate data to. You can specify the maximum number of replication reports that SyncIQ retains and the length of time that SyncIQ retains replication reports. Any files that do not meet the specified criteria are not replicated. You can interrupt replication jobs that target the local cluster. This option will affect only policies that specify the target cluster as a SmartConnect zone. # isi_audit_viewer -t protocol -s -e | grep -i . Matches any string in place of the asterisk. I am trying to set up an Audit Admins user that would be able to run this command, but they wouldn’t be able to do anything else. If the policy excludes However, if the action of the replication policy is set to copy, any file that was deleted on the primary cluster will be present on the secondary cluster. Failover and failback can be useful in disaster recovery procedures. However, resetting the policy causes a full or differential replication to be performed the next time the policy is run. However, you can configure how long archival snapshots are retained on the target cluster. Data failover is the process of preparing data on a secondary cluster to be modified by clients. Review the current settings of the replication policy. File sizes are represented in multiples of 1024, not 1000. Isilon clusters support IEEE Std 1003.2 (POSIX.2) regular expressions. You can view or edit settings for the policy by clicking the policy name. For example, if the target directory is a compliance directory, the source must also be a compliance directory. Includes or excludes files based on one of the following file-system object types: You can configure default settings for replication policies. RPO is the maximum amount of time for which data is lost if a cluster suddenly becomes unavailable. You can view the information contained in changelists. The Active Jobs table. When the source cluster becomes available again, you can fail back the data to the source cluster. You can modify, view, enable and disable replication policies. Allow Writes. Alternatively, you can filter file names by using POSIX regular-expression (regex) text. You can replicate data at the directory level while optionally excluding specific files and sub-directories from being replicated. Complete the following procedure for each replication policy that you want to fail over. If the last replication job completed successfully and a replication job is not currently running, select You might want to manually break a target association if an association is obsolete. Determines whether the policy can connect to all nodes on the target cluster or can connect only to specific nodes. Deleting files on the source cluster improves performance on the source cluster while maintaining the deleted files on the target cluster. During a differential replication, SyncIQ first checks whether a file already exists on the target cluster and then transfers only data that does not already exist on the target cluster.
