Description Bryn M. Reeves 2006-07-13 12:20:29 EDT

Problem Description
-------------------
On zSeries machines, zSeries Fibre Channel Adapter devices are brought online by
the zcfpconf.sh script provided in s390utils:

[ -x /sbin/zfcpconf.sh ] && /sbin/zfcpconf.sh

This is called from rc.sysinit after initial LVM setup completes so any LVM PVs
present on zfcp devices are not discovered by the initial vgscan/vgchange.

A second pass LVM init is carried out, but only if an /etc/mdadm.conf file for
Software RAID exists.


Steps to reproduce
------------------
1. Create an LVM2 volume group on zfcp attached storage
2. Confirm the VG is accessible
3. Reboot the system
4. Run vgs or vgdisplay

Actual Result:
The VG on zfcp storage is not shown.

Expected Result:
The VG on zfcp storage is activated at boot.

Created attachment 132384 [details]
proposed patch to rc.sysinit

Proposed patch to rc.sysinit attached:

- Move mdadm-specifics out of 2nd pass LVM activation 
- Add check for /etc/multipath.conf before mp initialization
- Add check for /etc/zfcp.conf to 2nd pass LVM activation

Comment 2 Bill Nottingham 2006-07-13 13:29:29 EDT

Why not just move it earlier?
