We run a lot of our SLES 9 servers on IBM Blades here.
My question is how do others that run IBM Blades configure the
networking and SAN.
For Networking the blades show up with 2 "Broadcom Corporation
NetXtreme BCM5704S Gigabit Ethernet (rev 02)"
To configure these and use vlan's i have to download the bcm5700 and
basp drivers from broadcom and setup /etc/basp/team-vlan. I've looked
at the newer tg driver and it doesn't have anywhere to say what vlan
to use? Anyone else BCM5704S's on vlans? Do you use something besides
the basp driver?
For SAN, we sanboot, the blades have 2 "QLogic Corp. QLA2312 Fibre
Channel Adapter (rev 02)". I use the qla2300 driver that comes with
the sles kernel and this line in /etc/modprobe.conf.local.
options qla2xxx ql2xmaxqdepth=16 qlport_down_retry=8 \
ql2xloginretrycount=8 ql2xfailover=1 ql2xlbType=1
This gets multipathing working if i have multiple paths to the same
disk though one SVC (a san device that manages our disks). If i enable
the second SVC (required for SVC failover) i see two disks. I've tried
multipath-tools to combine these two disks into one disk in
devicemapper but i get odd errors and or it runs and nothing shows up.
How do others have it configured with multipaths to the same disk
using qlogic cards. Does anyone have multipath-tools working on qlogic
cards or a blade?
Thanks
Eli
