A meta device enables you to aggregate thin devices or regular devices to increase the device size.
You can create a meta device with a thin device as the head and create other thin devices as members, or you can create a meta device with a regular device as the head and create other regular devices as members. The total meta device size is the combination of the head size and all the member device sizes.
Note | There is no delete action for a meta device. Removing the members from a meta device results in a thin device. |

A meta member device (also referred to as a Meta LUN) is a LUN that is composed of several elements (LUNs). Meta member devices are similar to private LUNs. A meta member device is used by the system and is not available directly to any host. For example, you cannot place a meta member device into a storage group. There are two types of meta member devices:
Concatenated Meta LUN—Creates a larger LUN from smaller LUNs and when performance is not a high priority.

VMAX designates three types of auto-provisioning groups: storage groups, port groups, and initiator groups. These three groups work together as a masking view.
The masking view ensures that the target initiators in an initiator group can access the target storage resources in a storage group by means of the target ports in a port group.
Masking views are also useful for making changes to how the storage is presented. Changes to groups that belong to a masking view, such as adding a device or port, are automatically reflected in the masking view.

FAST automatically moves the data to high-performance storage tiers and moves the inactive data to low-cost, but high-capacity storage tiers. Policies dictate how the performance and cost are optimized while the automation of FAST means that your storage system has no added management constraints compared with slower and more expensive systems. A FAST system always monitors and identifies the current activity levels of your data and moves the active data and inactive data to the most appropriate storage tier (according to your policy).
A FAST policy is a set of tier usage rules that are applied to your storage groups. A FAST policy describes up to three tiers and assigns an upper usage limit for each tier. The usage limit specifies the maximum percentage of the storage group that the FAST controller can allocate to a particular tier. Policy settings allow you to control and manage automated activity.

In earlier UCSD releases, when executing VMAX workflows, sometimes you will see the following error:
The SYMAPI database file is already locked by another process.
This happens when executing multiple Tasks/Actions concurrently.
To overcome this issue, you must resubmit the SR/action.
To reduce the user intervention in handling such scenarios, we have added logic to re-submit the task/action automatically. The new logic will resubmit the Task/Action the specified number of times.
These configurations can be configured in the vmax.properties file, available in the /opt/infra/inframgr folder.
The vmax.properties file consists of following parameters:
emc.vmax.retryMessages |
This parameter sets the error messages. If this error message is captured for any of the Tasks/Actions, the same Tasks/Actions will be executed. |
Default Error Message: The SYMAPI database file is already locked by another process
|
||
emc.vmax.maxIterationCount |
This parameter specifies the maximum number of attempts to be tried if the VMAX response contains the message specified in the property mentioned above. |
Default value: 20 |
||
emc.vmax.sleepTime |
This parameter sets the time (in ms) the retry operation waits before it connects to the VMAX device to execute the command. |
Default value: 30000 ms (30 sec) |
VMAX Sym Device Inventory Collection
UCSD collects the sym device inventory for every 500 devices. This also can be configured using vmax.properties file.
