Hy all,
thanks for your answers, i tried your suggestions.
This is how it works for Suse Prof 8.2 / SLES 8 SP3 / SLES 9 SP1.
For some reason i had to run the SANsurfer FC HBA Manager for Linux (32bit)
(you can get it from qlogic's website) before any LUN's (new SAN-Disks)
could be detected at runtime.
SANsurfer ask for a initial configuration for each adapter.
then type
echo "scsi-qlascan" > /proc/scsi/qla2xxx/0
to rescan the fibrechannel bus.
(at Suse 8.2 and SLES 8 the directory name is qla2300 instead qla2xxx)
now the Qlogic Adapter has recogniced the new disks which can be verified
with
cat /proc/scsi/qla2xxx/0
SCSI LUN Information:
(Id:Lun) * - indicates lun is not registered with the OS.
( 0: 0): Total reqs 0, Pending reqs 0, flags 0x0*, 0:0:81 00
-> the last line indicates the new disk found
next step is to make the disks visible to the OS (scsi-layer)
q20ap1:/proc/scsi # echo "scsi add-single-device 0 0 0 0" > /proc/scsi/scsi
the last step can also be accomplished by using /bin/rescan-scsi-bus.sh
script which is shipped with the "scsi" RPM-Package.
-> it only detects all new disks with additional command-line parameters
(e.g. -l -w -c)
all disks should now be visible, for example by typing
cat /proc/partitions
regards
Frank
