---Problem Description---
Fail to active the second DS8K fcp lun permanently
Machine Type = z13 lpar
---Debugger---
A debugger is not configured
---Steps to Reproduce---
1. Map tow fcp luns from DS8880:
root@ilz62u:~# lsluns
Scanning for LUNs on adapter 0.0.1800
at port 0x50050763070057f9:
0x4000402800000000
0x4001401000000000
Scanning for LUNs on adapter 0.0.1900
at port 0x50050763070b17f9:
0x4000402800000000
0x4001401000000000
2. active the two fcp temporarily
echo 0x4001401000000000 > /sys/bus/ccw/drivers/zfcp/0.0.1800/0x50050763070057f9/unit_add
echo 0x4001401000000000 > /sys/bus/ccw/drivers/zfcp/0.0.1900/0x50050763070b17f9/unit_add
3. active them via tool "chzdev" permanently
root@ilz62u:~# lszdev | grep 57f9
zfcp-lun 0.0.1800:0x50050763070057f9:0x4000402800000000 yes yes sdas sg44
zfcp-lun 0.0.1800:0x50050763070057f9:0x4001401000000000 yes yes sdau sg46
4. multipath show
root@ilz62u:~# multipath -ll | grep 2107s
d2ilsd2107s (36005076307ffd7f90000000000000110) dm-15 IBM,2107900
d1ilsd2107s (36005076307ffd7f90000000000000028) dm-14 IBM,2107900
5. reboot
6. the secod fcp lun "0x4001401000000000" fail to keep active any more
root@ilz62u:/sys/bus/ccw/drivers/zfcp/0.0.1800# ls 0x50050763070057f9
0x4000402800000000 access_denied failed in_recovery power status uevent unit_add unit_remove
root@ilz62u:/sys/bus/ccw/drivers/zfcp/0.0.1900# ls 0x50050763070b17f9

root@ilz62u:/sys/bus/ccw/drivers/zfcp/0.0.1900# multipath -ll | grep 2107s
d1ilsd2107s (36005076307ffd7f90000000000000028) dm-14 IBM,2107900
Stack trace output:
no
Oops output:
no
System Dump Info:
The system is not configured to capture a system dump.
== Comment: #1 - Heinz-Werner Seeck <heinz-werner_seeck@de.ibm.com> - 2017-04-18 03:08:54 ==
First problem evaluation:
Could be a chzdev problem. Seeing two jump-labels in the udev rule for port 0x50050763070b17f9 on fcp device 0x1800 and 0x1900. The first label enables the LUN that is working, while the second one with the LUN number that is not working is likely ignored.
Confirmed as a bug in chzdev!
Workaround:
Use chzdev to configure and immediately deconfigure a non-existent FCP LUN for the FCP devices that displays the problem.
Example (ignore any warnings that might show up):
For FCP device 0x1800:
chzdev -e -p zfcp-lun 0x1800:0x0000000000000000:0x0000000000000000
chzdev -d -p zfcp-lun 0x1800:0x0000000000000000:0x0000000000000000
and for FCP device 0x1900:
chzdev -e -p zfcp-lun 0x1900:0x0000000000000000:0x0000000000000000
chzdev -d -p zfcp-lun 0x1900:0x0000000000000000:0x0000000000000000
Solution available : Patch applied:
Upstream patch, also applies to s390-tools v1.37.0 and v1.37.1. |
[Impact]
* out of order devices fail to activate
[Test Case]
* See steps to reproduce below
[Regression Potential]
* s390-tools rebuild, includes rebuilding the bootloader, thus failure to boot should be tested in case of a no-change rebuild regression. The fix for the issue in question is a pure ordering issue, thus ordering the ids should resolve the issue at hand without any other negative side-effects
