West realized the potential for more advanced and openly compatible data-storage devices, as did competitors such as Digital Equipment Corporation with their StorageWorks product. Features mentioned in the patent paperwork included optional hot swapping ,  guide rails for proper electrical contact, and a method to lock the drives in place once they were secured in the disk enclosure. A special model was the IP, offering IP-based access to storage. Within a couple of years,[ when? Later in , the line was expanded to include a new entry-level storage system, the CX The form factor is a half-width 1U or 2U device known as an X-blade, two of which are mounted side by side in the storage processor enclosure.

You can use it for storage provisioning and manage array configurations from any one of the managed storage system on the LAN. It can also be used to automate the management functions through shell scripts and batch files.
CLI commands for many functions are server based and are provided with the host agent. The remaining CLI commands are web-based and are provided with the software that runs in storage system service processors SPs. This host will be used to configure the storage system. But, this will still get the typical storage array jobs done.
Secure CLI is most secured and preferred interface. The default, if you omit this switch, is localhost. Create Storage Group The next several examples will shows how to create a storage group and connect a host to it.
This is the number that host will see from its end. Alu is the array LUN number, which storage system will see from its end. Register the Host Register the host as shown below by specificing the name of the host. Connect Host to Storage Group Finally, connect the host to the storage group as shown below by using -connecthost option as shown below. You should also specify the storagegroup name appropriately.
View Storage Group Details Execute the following command to verify the details of an existing storage group. Copy Data to Hotspare Disk The naviseccli command initiates the copying of data from a failing disk to an existing hot spare while the original disk is still functioning.
Once the copy is made, the failing disk will be faulted and the hotspare will be activated. When the faulted disk is replaced, the replacement will be copied back from the hot spare. To display the current migration sessions and its properties: naviseccli migrate —list The stripe expansion may take a long time to complete. There is no restriping of data between the original storage and the new LUNs.
The concatenate operation completes immediately To create or expand a existing metaLUN, use the below command. In this example, it will destory metaLUN number 5.
