Item Description
Hitachi HDS 9980V
There are certain specific “host mode” settings
required on the Hitachi arrays in order to allow
LifeKeeper to work properly in this kind of
directly connected configuration.For the 9570V
array, the following settings are required:
Host connection mode1 --> Standard mode
Host connection mode2 --> Target Reset mode
(Bus Device Reset)
Third Party Process
Logout Spread mode
LIP port all reset mode --> LIP port all reset
mode
For the 9970V and 9980V arrays, the “host
mode” must be set to “SUN”.The HDS 9980V
was tested by a SIOS Technology Corp. partner
organization in a multipath configuration using
DMMP on SLES9 SP3 with LSI Logic Fusion
HBAs. Refer to theDevice Mapper Multipath I/O
Configurations section for details.
nStor NexStor 4320F
This storage was tested by a SIOS Technology
Corp. partner organization, in a dual controller
configuration with each server in a 2-node
cluster directly connected to a separate
controller in the array. With this configuration,
the LifeKeeper behavior in a split-brain scenario
is the same as that described above for the
Hitachi HDS storage arrays, and the same
hierarchy configuration precautions should be
observed.
ADTX ArrayMasStor
L and FC-II
These storage units were tested by a SIOS
Technology Corp. partner organization, both in a
single path configuration with a switch and in a
dual controller configuration with each server in a
2-node cluster directly connected to a separate
controller in the array. In both configurations, the
LifeKeeper behavior in a split-brain scenario is
the same as that described above for the Hitachi
HDS storage arrays, and the same hierarchy
configuration precautions should be
observed.The ArrayMasStor L was also tested
and certified by our partner organization in a
multipath configuration using QLogic 2340 and
2310 host bus adapters and the QLogic failover
driver, version 6.06.10.
