Component Location and Identification
Some storage area procedures, such as reconfiguration, can cause the affected
switches to pause. If the pause is long enough, I/O failure occurs on all paths
connected to that switch. If both the primary and the backup paths are connected to
the same switch, the LDEV goes down.
Refer to the documentation that accompanies the ESS.
Component Location and Identification
Topics discussed in this subsection are:
The location and identification of a component in an Integrity NonStop NS1000 server
is similar to that of the Integrity NonStop NS-series server. For a general description of
the location and identification of components, refer to the NonStop NS-Series Planning
Guide. Details about the location and identification components that are specific to an
Integrity NonStop NS1000 server are presented here.
Terminology
Terms specific to an Integrity NonStop NS1000 system that are used in locating and
describing components are:
On Integrity NonStop NS-series systems, locations of the modular components are
identified by:
•
Physical location:
°
Rack number
°
Rack offset
•
Logical location: group, module, and slot (GMS) notation

Term Definition
Blade complex In an Integrity NonStop NS1000 system, OSM uses this term to
hierarchically differentiate between each blade element. See
Blade Complex
on page 4-2.
Blade element An HP Integrity rx2620 server that contains the PE, power
supplies, fan assemblies, and firmware. An Integrity NonStop
NS1000 system includes up to eight blade elements.
