Context config>card
Description This mandatory command enables access to a card's MDA CLI context to configure MDAs.

Cards inserted in expansion slots are numbered 2.
Values
mda-type
Syntax mda-type mda-type
no mda-type
Context config>card>mda
Description This mandatory command provisions a specific MDA type to the device configuration for the slot. The
MDA can be preprovisioned but an MDA must be provisioned before ports can be configured. Ports can be
configured once the MDA is properly provisioned. On 7210 SAS-R6, this command must be used to
configure the type of MDA.
7210 SAS-M (all variants of the platform) and 7210 SAS-X platform supports a fixed MDA. The fixed
MDA (addressed as mda 1) is auto-equipped and auto-provisioned on bootup. It cannot be deleted. An error
message is shown in case the no form of command is performed on fixed MDAs.
All 7210 SAS-M platform variants supports an expansion slot which can accept supported MDA types. The
MDA in the expansion slot is addressed as mda 2. Users must use this command to configure the MDA slot
appropriately based on the supported MDA cards they plan to use. To modify an MDA slot, shut down all
port associations. An alarm is raised if partial or complete MDA failure is detected. The alarm is cleared
when the error condition ceases.
NOTES:
• 7210 SAS-X does not support any expansion slot. It does not support use of this command.
• 7210 SAS-M, X, T, and R6 are auto-provisioned. Except for the CES MDA and the 2x10G MDA.
The no form of this command deletes the MDA from the configuration. The MDA must be administratively
shut down before it can be deleted from the configuration.
