MAP3280 storage enclosure installation
failed: at least one DDM is missing, unplugged, or bypassed
The installation for the storage enclosures that you are
installing failed because a DDM was bypassed.
MAP3280 Section-1
Procedure
- Select the rack model that
applies:
- 941/94E, continue at the next step.
- 951/95E or
961/96E, go to step 4.
- Refer to the FRU list in the serviceable event that
sent you here.
- For each DDM in the FRU list, read the location code. The location code is the special format that is used during
MES and installations. An example of a location code is Rw-Sxy-P1-Dz,
where:
- w = 1–5, the rack number
- x = 1, the front storage enclosure and x = 2, the
rear storage enclosure
- y = 1–8, the storage enclosure location, top to
bottom
- z = slot 1–16, the DDM slot location
- For each location code, locate the physical location
by using Figure 1, Figure 2, and Figure 3.

- The normal serviceable event FRU replace
procedure cannot be used. The code objects are not yet created because
the installation failed. Continue with the following steps:
- Replace each DDM in the FRU list with a new DDM now.
The DDM can be hot-plugged with no damage to the storage enclosure
and DDM.
- Wait for the new DDMs to be in the ready state before
you go to step 7.
- Refer to the FRU list in
the serviceable event that sent you here.
- For each DDM in the FRU list, read the location code.
The location code is the special format that is used during MES and
installations. An example of a location code is Rw-Gx-P1-Dz,
where:
- w = 1–4, the rack number
- x = 01–20, storage enclosure location, top to bottom
- z = slot 1–24, the DDM slot location
- For each location code, locate the physical location by using Figure 4, Figure 5,
Figure 6, and Figure 7.

- The normal serviceable event FRU replace
procedure cannot be used. The code objects are not yet created because
the installation failed. Continue with the following steps:
- Replace each DDM in the FRU list with a new DDM now.
The DDM can be hot-plugged with no damage to the storage enclosure
and DDM.
- Is the DDM green activity LED
indicator
lit solid or flashing? - Yes, go to the next step.
- No, try reseating the DDM. If it still fails, replace the
DDM with another new DDM. If it still fails, replace the storage enclosure
midplane FRU.
Note: You cannot use normal guided maintenance to replace
the midplane because the installation failed before all the needed
code objects were created. Instead, remove all power from the storage
enclosure and refer to the "Exchange the storage enclosure midplane"
procedure in the Exchanging Parts section of this service information
center. After the new midplane is installed, reconnect all storage
enclosure power.
- Are there any other open serviceable events for the storage enclosures that you are installing?
- Yes, if the other serviceable event also includes
SRC BE340080 or BE34004D, use this MAP to replace the
listed FRUs.
- If the other serviceable event includes a
different SRC that cannot be repaired, stop and contact your next
level of support.
- Close the open serviceable events for
the storage enclosures that you are installing.
- Retry the storage enclosure installation procedure:
- Do not disconnect any of the FC-AL cables from the storage
enclosures that you are installing.
- As you go through the installation procedure, ignore
any instructions to connect the cables; they are already connected.
- The installation process installs the storage enclosures
and provides a "FRU verification test" for the DDMs that you replaced.
If the installation fails with the same SRC and DDM, contact your next
level of support.
- Exit this procedure and complete the installation.
