The 7210 SAS auto-provisions card and MDA types.
On 7210 SAS platforms, where cards/MDAs are not auto-provisioned, to initialize a card, the chassis slot, line card type, and MDA type must match the preprovisioned parameters. In this context, preprovisioning means to configure the entity type (such as the line card type, MDA type, port, and interface) that is planned for a chassis slot, line card, or MDA. Preprovisioned entities can be installed but not enabled or the slots can be configured but remain empty until populated. Provisioning means that the preprovisioned entity is installed and enabled.
You can:
Preprovision ports and interfaces after the line card and MDA types are specified.
Install line cards in slots with no preconfiguration parameters specified. When the card is installed, the card and MDA types must be specified. This is required on 7210 SAS chassis based platforms or on those platforms that support expansion slots. Typically, on 7210 SAS platforms that do not support any removable cards and MDAs, the cards are preprovisioned for fixed ports.
Install a line card in a slot provisioned for a different card type (the card will not initialize). The existing card and MDA configuration must be deleted and replaced with the current information. This is required on 7210 SAS chassis based platforms or on those platforms that support expansion slots. Typically, on 7210 SAS platforms that do not support any removable cards and MDAs, the MDAs are preprovisioned for all fixed ports.
