With RHEL4 kernel-smp-2.6.9-17.EL.i686.rpm
and device-mapper-multipath-0.4.5-5.2.RHEL4.i386.rpm
there is no SCSI subsystem specific agents in
/etc/hotplug/<name>.agent for handling the addition/deletion of SCSI
devices. There is file /etc/dev.d/block/multipath.dev which has to be
used for online addition/deletion of devices. Can some one explain me on how the
new SCSI device gets added/deleted using hotplug
and who calls “/etc/dev.d/block/multipath.dev” for
refreshing the multipathing maps? Also if the device is partitioned, the new device
node (/dev/dm-*) for partitioned segment is not created until “kpartx –a
<whole device-name> is
issued from the command line. Will the /sbin/hotplug
be called when the device is partitioned (using fdisk)? And how to configure
hotplug to call “kpartx “
whenever a partition is added/deleted? Thanks and regards -Murthy |
