Note: These preparation activities should be accomplished before servicing, to minimize the
number of activities that must be performed while the enclosure is open. Staying within the
enclosure servicing window is critical to maintaining its thermal operating requirements.
Step 4 : If the Rear Fans or PSUs require replacement, start with these CRUs as they are external and do
not require opening the enclosure. Access the rear of the enclosure and follow the appropriate
procedure for replacing these CRUs.
Step 5 : For replacement of internal CRUs, pull the enclosure out of the rack to allow access to the
inside of the enclosure. The enclosure can stay in this position for a maximum of 5 minutes in an
ambient temperature of 5°C to 35°C (de-rated for elevation).
Step 6 : If an IOM Fan has faulted, replace this CRU first. Remove the IOM Fan and install the replacement
in 30 seconds or less.
Step 7 : If an IOM has faulted, replace this CRU next. Remove the IOM and install the replacement in 1
minute or less.
Step 8 : If any Drive Assemblies have faulted, replace each device in a sequential fashion. Pay close
attention to proper orientation of the device within the enclosure. Replace each device in 1
minute or less.
Step 9 : Perform a visual inspection of the enclousre to ensure that all CRUs are seated properly.
Step 10 : Before the 5-minute servicing window expires, push the enclosure back into the rack. If there
are additional internal CRUs that require replacement, wait 10 minutes before repeating this
procedure, beginning with step
Step 11 : After all CRUs have been replaced, verify remotely that the CRU replacements were successful
and that enclosure function has returned to 100%.
3.2 IOM Replacement
Before you begin:
Important: Standard zoning methods (i.e. WDDCS Tool, OOBM, sg_senddiag, or SMP zoning
commands) require each IOM to be configured individually. After replacing an IOM, zoning
should be configured on it before the system is put back into production, otherwise, any host
that is booted and has access to that IOM will see all drives. File-based zoning does not require
individual IOM zoning configuration after replacement, as the zoning configuration is stored on
the baseboard.
Note: Enclosures running firmware version 3000-058 or later are equipped with Auto-Sync,
a feature that automatically detects a mismatch of SEP and OOBM firmware between an
enclosure's two IOMs and synchronizes the firmware versions. See
212)
for more details and instructions for enabling this feature.
