Storage and Adapter Configuration
Item Description
Special Considerations for Switchovers with
Large Storage Configurations
With some large storage configurations (for
example, multiple logical volume groups with 10
or more LUNs in each volume group), LifeKeeper
may not be able to complete a sendevent within
the default timeout of 300 seconds when a
failure is detected. This results in the
switchover to the backup system failing. All
resources are not brought in-service and an error
message is logged in the LifeKeeper log.
The recommendation with large storage
configurations is to change SCSIERROR from
“event” to “halt” in the
/etc/default/LifeKeeper file. This will
cause LifeKeeper to perform a “halt” on a SCSI
error. LifeKeeper will then perform a successful
failover to the backup system.

HP 3PAR F200/F400/T400/T800
The HP 3PAR was tested by a SIOS
Technology Corp. partner with the following
configurations: HP 3PAR T400 (Firmware
(InForm OS) version 2.3.1 MU4) using HP 82Q
8Gb Dual Port PCI-e FC HBA AJ764A
(Firmware version 5.03.02, driver version
8.03.01.05.05.06-k) with DMMP (device-
mapper-1.02.55-2.el5, device-mapper-multipath-
0.4.7-42.el5).
The test was performed with LifeKeeper for
Linux v7.3 using RHEL 5.6 (kernel 2.6.18-
238.el5).
See the Device Mapper Multipath I/O
Configurations section also, especially in the
case of F400.
