Procedure to enable/disable auto meta using Solution Enabler SYMCLI and SMC.

Solution:

If you want to create a single regular device larger than the maximum size, Symmetrix will create a metadevice instead when auto meta feature is enabled. If auto meta is disabled (which is by default), creating device fails. Auto meta feature was introduced with Solutions Enabler V6.5.1 running Enginuity version 5773, which allows metadevices to be created in a single configuration change session.

For Enginuity 5874, the maximum device size in cylinders is 262668.

For Enginuity 5773 and earlier, the maximum device size in cylinders is 65520.

Auto meta can be enabled only if the other auto meta parameters min_auto_meta_size, auto_meta_config and auto_meta_member_size are set to valid values. The settings are Symmetrix-wide.

Min_auto_meta_size: Specifies the size threshold that triggers auto meta creation. When you try to create a device greater than min_auto_meta_size and auto_meta is enabled then a meta will be created. The min_auto_meta_size cannot be set less than the auto_meta_member_size, and needs to be less than or equal to the value in the table below.

Auto_meta_member_size: Specifies the default meta member size in cylinders when the auto_meta feature is enabled. Needs to be less than or equal to the value in the table below.

Auto_meta_config: Specifies the default meta config when the auto_meta feature is enabled. Possible values are CONCATENATED, STRIPED, or NONE.

Enginuity version	Max single device size (CYL)	Max single device size (GB)	Min_auto-meta_size (CYL)	Auto_meta_member_size (CYL)
5874	262668	240	262669	262668
5773	65520	59	65521	65520

To enable auto meta using Solution Enabler:

1. Run the following command to verify if auto meta is disabled: symcfg list -sid xxxx -v
2. If not, create a file 1.txt and add the following text: set Symmetrix auto_meta=enable, min_auto_meta_size=xxxx, auto_meta_member_size=xxxx, auto_meta_config=xxxx;
3. Run the following command: symconfigure -sid xxxx -f 1.txt commit -nop
4. Verify if auto meta is enabled.

To enable the auto meta using SMC:

1. Right-click the Symmetrix ID and select Symmetrix Admin, Set Symmetrix Attributes
2. Enable Auto Meta feature, and enter the Minimum Auto Meta Size, Auto Meta Member Size, Auto Meta Configuration.
3. Click Add to Configure Session List and Commit the change.
