PSU             DVDU           FAN_A      FANBP_B    OPNL

The components which must be Cold Replaced on M4000/M5000 are:

MBU_A           MBU_B          CMU_A      MEMB       DIMM
DDC_A           DDC_B          XSCFU      IOU        DDCR

HDDBP           TAPEBP         DVD        DVDBP_A    DVDBP_B
OPNL

The components which must be Cold Replaced on M8000/M9000 are:

XBU_B           CLKU_B         OPNL       SNSU       ACS_A
ACS_B           ACS_C          ACS_D      ACSTPH_A   ACSTPH_B
ACSTPH-C        ACSTPH-D       BP_A       BP_B       PSUBP_A
PSUBP_B         FANBP_A        FANBP_B    FANBP_C    MEDBP
SWBP           RDPF

The following steps are simply a reference to make one aware of what is involved in the Cold Replacement Method process, but the Service Manual is the authoritative resource for the actual process to be followed.

• Shut down all applications (if running) on all domains on platform.

• Shut down all domains.

• Power off the platform.

• Unplug the power cords (Make sure to be at the same potential as the system).

• Initiate FRU replacement.

• Power on the platform and verify FRU replacement is successful.

• Bring domains and applications back online.

Hot Replacement Method

Hot Replacement Method requires that the domain(s) containing the faulty FRU be shut down in order to replace it.  The remainder of the platform can stay in operation during the service period. Fans and PSUs are not part of domains and can therefore be replaced while all domains are running. Special rules apply for these FRUs to guarantee redundancy during the replacement operation, they are described later in this document.

The components which can be Hot Replaced on M3000 are:

FAN_A           HDD          PSU

The components which can be Hot Replaced on M4000/M5000 are:

FAN_A           FAN_B          PSU

The components which can be Hot Replaced on M8000/M9000 are:

CMU             CPUM_A         CPUM_B     DIMM         IOU
HDD             PCICS          IOUA       PCIB-EX      XSCFU_B
XSCFU_C         PSU            FAN_A      FAN_B        DDC_A
DVDU            TAPEU

The following steps are simply a reference to make one aware of what is involved in the Hot Replacement Method process, but the Service Manual is the authoritative resource for the actual process to be followed.

• Shut down applications (if running) on domains that contain the FRU.

• Shut down domains that contain the FRU.

• Initiate FRU replacement.

• Verify FRU replacement is successful.

• Bring affected domains and applications back online.

Active Replacement Method

Active Replacement Method can only be used on redundantly configured FRUs that can be Dynamically Reconfigured (DR) into or out of a domain.  No interruption to domain or platform operations will occur when utilizing this method. Fans and PSUs are not part of domains and can therefore be replaced while all domains are running

The components which can be Active Replaced on M3000 are:

HDD             PSU          FAN_A

The components which can be Active Replaced on M4000/M5000 are:

PCICS           HDD          TAPE

The components which can be Active Replaced on M8000/M9000 are:

CMU             CPUM_A         CPUM_B     DIMM         IOU
HDD             PCICS          IOUA       PCIB-EX      XSCFU_B
XSCFU_C         DVDU           TAPEU      PSU          FAN_A
FAN_B           DDC_A

The following steps are simply a reference to make one aware of what is involved in the Active Replacement Method process, but the Service Manual is the authoritative resource for the actual process to be followed.

• Verify the FRU is redundantly configured in all domains in which this FRU is configured.

• Verify the FRU and all dependent hardware on the FRU (I/O adapters, etc) are inactive.

• Verify that resources are switched to alternate paths (I/O, network, etc) if necessary.  This may include breaking disk mirrors or utilizing multi-pathing software to perform the actions.

• Initiate FRU replacement utilizing Dynamic Reconfiguration.

• Verify FRU replacement is successful.

• Verify that any inactivated paths are re-enabled for all affected domains.  This may include syncing disk mirrors or utilizing multi-pathing software to perform the actions.

• Verify that the affected domains and applications are all still online without issues.
