What is psm lun in clariion

Right click on clariion array and check the connectivity status whether the initiators are showing. If it is showing check whether the initiators are logged in. If it is showing under connectivity status and registered status showing "NO" then you need to install Agent or else you need to register it manually.

If it is Registered and not logged in then you need to check the Zoning side and physical connectivity. If possible remove the zone and create it back. Once you create the zone dont forget to Enable and Save the config. After this just refresh it. Once all these tasks are fine then you can login to Navisphere and update the array once. Update is over then you can go to connectivity status and check. Dynamically increase LUN capacity.

Striped or concatenated. Data is restriped when a striped metaLUN is created. Appears to host as a single LUN. Added to storage group like any other LUN. Supported only on CX family with Navisphere 6. End-to-end data protection. Cache implementation. Provisioning and resource allocation. Memory budgets for caching and for snap sessions, mirrors, clones, copies.

Process Scheduling. Boot Management. Cache memory on an SP performs two tasks:. Staging: Temporary buffering of current read and write data. Storage: Repository for frequently accessed data. Maintaining copies of read and write data. User must explicitly enable this for both read and write. Write cache optimization. Locality - Merge several writes to the same area into a single operation. Increases write performance.

Immediacy - Satisfy user requests without going to the disks. Read cache optimization prefetching of data for sequential reads. Event Monitor is part of the Navisphere Agent.

CX3 code levels would have a 3 in front of it and so forth. Going back to the pre CX days FC , this 5 was still used in there. Failover mode: They are 4 types. As per best practice, failover mode 4 is suitable than others. Author : sanadmin. Related Posts. Next « Prev Post.

It determines which physical addresses each attached host will use for its LUNs. This feature is configurable by the storage admin. Access Logix limits host may be in 1 storage group per storage system. If you add the same host in another storage group it will be removed from the previous one.
