2.4 External configuration disks
On a configuration disk of a unit (MU, SU x86, HNC), the following data of the SE server
configuration are stored:
● General data of the SE server:
– Model, name and location
– Cross-unit data
● Unit-specific data with contents that should remain available even after the Unit fails or
is powered off (not for HNC):
– Model, SW version and host name
– IP configuration
– FC configuration
– VM data for BS2000 (on SU x86 also for Linux and Windows)
● Current configuration of the Net Unit switches
By default, the data are locally stored on an internally mirrored disk of the Unit (MU, SU x86,
HNC).
In addition to the internal configuration disk, up to two external configuration disks can be
configured on external FC RAID systems, to which all MUs and SU x86 have access via a
redundant connection.
This ensures consistency: Every MU and SU x86 reads the data of the SE server in the
same way and the actions on these units can be coordinated.
The SE Manager displays information about the configuration disks, e.g. of an MU, in the
Hardware → Units[ → <se server> (SE<model>)] → <unit> (MU) → Information menu (see
“Displaying configuration disks of the MU” on page 207):
