Hi
Has anybody experience with RHEL 4.0 and SLES 9.0 on P5 ?
I have Problems with the bonding Device with 2 VIO Servers to bring up the Interfaces in the arp Monitoring Mode.
What is the best way to resync/recreate the Linux RAID1 Mirror when 1 Mirror( VIO-Server ) will go down ?
Even i reboot one VIO-Server my Raid looks like this:
md2 : active raid1 sdb1[0]
10485632 blocks [2/1] [U_]
where is sdd1 ?
md1 : active raid1 sdc4[1]
9825216 blocks [2/1] [_U]
where is sda4 ?
md0 : inactive
unused devices: <none>
Why is my md0 inavtive ( swap ) ?

sda is on vio1
sdc is on vio2
both are SAN Disks direct attached over vscsi ( no lv )
If i reboot my LPAR:
