3.2 Types of Maintenance for the Link Card


3.2 Types of Maintenance for the Link Card
This section describes the types of maintenance for the link card.
The link card is mounted in the PCI Express (PCIe) slot of the SPARC M12-1/M12-2/M12-2S/M10-1/M10-4/M10-4S.
Table 3-4 lists the types of maintenance for the link card. The link card maintenance type refers to the status at the server. The terms are defined as follows:
Definition According to the System Operation Status
The types of maintenance depend on the system operation status during maintenance. The supported maintenance is divided into three types: active maintenance, inactive maintenance, and system-stopped maintenance.
  1. Active maintenance
    Maintenance is performed when the physical partition to which a FRU requiring maintenance is assigned is operating.
  2. Inactive maintenance
    Maintenance is performed when the physical partition to which a FRU requiring maintenance is assigned is stopped.
  3. System-stopped maintenance
    Maintenance is performed with all physical partitions stopped.
Definition According to the Power Supply Status
In addition, for each of the three: "Definition according to the system operation status," there are two types: hot maintenance and cold maintenance.
  1. Hot maintenance
    Maintenance is performed with the power cord of the server requiring maintenance connected.
  2. Cold maintenance
    Maintenance is performed with the power cord of the server requiring maintenance removed.

*1 It is necessary to use PCI Hot Plug (PHP) to release the link card from the system. If the setting for the direct I/O function is enabled, then maintenance with the system stopped must be performed because the link card cannot use PHP.
*2 It is necessary to use PCI Hot Plug (PHP) to release the link card from the system. If the setting for the direct I/O function is enabled, the link card cannot use PHP. Using physical partition dynamic reconfiguration (DR), release the link card from the system.
*3 Using physical partition dynamic reconfiguration (DR), it is necessary to release the server containing the link card from the physical partition.
