Bug#486946: FCP problem on Debian s390 hardware

[Shrirang B Kulkarni1 <shrirkul@in.ibm.com>]

package: zfcp
Version: 2.6.18-6-s390
Severity: important


I installed Debian (2.6.18-6-s390) on one my guest image on z/VM. The
Guest has both DASD and FCP attached to it.
I created / and swap on DASD.
At install time Debian was not showing any FCP which is attached to
Guest image thought let me try to enable same after install of OS.

Once Install was done went to

Steps
1. chccwdev -e 0.0.b001

2. echo 0x5005076305080310 > /sys/bus/ccw/devices/0.0.b001/port_add

3. echo 0x4010400100000000 >
/sys/bus/ccw/devices/0.0.b001/0x5005076305080310/

enabled all SCSI devices of FCP

4. cd /sys/bus/ccw/devices/0.0.b001/0x5005076305080310/

5. /sys/bus/ccw/devices/0.0.b001/0x5005076305080310 # ls

0x4010400100000000 0x4010400b00000000 0x4010401500000000
0x4011400a00000000 0x4011401400000000 0x4011401e00000000

6. So able to see all devices on FCP and made partions and mounted able to
use in Debian Linux

7. I tried to create initrd as new devices added by

mkinitrams -o initrd.img-2.6.18-6-s390 2.6.18-6

8.  But when i reboot machine No FCP devices detected.

Once again I need repeat 1-6 steps for FCP to get enable
