ViPR 2.1 - Using ViPR with Existing Environments
Table of Contents
The mechanism for bringing storage under ViPR control is referred to as ingestion.
Where you are using ViPR object storage, file system data can be ingested into ViPR as object data and accessed using the supported object protocols or as a Hadoop Distributed File System (HDFS). ViPR also provides the ability to ingest volumes that are part of a VPLEX configuration, or that are protected using RecoverPoint (RP) or Symmetrix Remote Protection Facility (SRDF).
The way in which existing storage has been provisioned on an array affects the ability of ViPR to ingest block volumes or file systems from the array, and can affect future provisioning operations. The following table lists the import mechanisms that are provided and identifies any limitations.Back to Top
- If you use the element manager to create a volume, and at the same time another user tries to run the "Create a Volume" service from ViPR on the same storage system, the storage system may be locked by the operation run from the element manager, causing the ViPR “Create a Volume” operation to fail.
- After a volume was exported to a host through ViPR, the same masking view, which was used by ViPR during the export, was changed on the storage system through the element manager. When ViPR attempts to use the masking view again, the operation will fails because what ViPR has in the database for the masking view is not the same as the actual masking view reconfigured on the storage system.
Once a filesystem is under ViPR management, and has been provisioned or exported to a host through a ViPR service, you should no longer use the storage system element manager to provision or export the filesystem to hosts. Using only ViPR to manage the volume will prevent conflicts between the storage system database and the ViPR database, as well as avoid concurrent lock operations being sent to the storage system. You can however continue to use the storage system element manager to manage storage pools, add capacity, and troubleshoot ViPR issues.Back to Top
