From 09b7985cf611df26fc756e0b8025a260fc4a4948 Mon Sep 17 00:00:00 2001 From: "christophe.varoqui@free.fr" Date: Fri, 13 Feb 2004 00:53:10 -0800 Subject: [PATCH] more udev-016/extras/multipath incremental to udev-016/extras/multipath-0.0.16.3, * add a GROUP_BY_SERIAL flag. This should be useful for controlers that activate their spare paths on simple IO submition with a penalty. The StorageWorks HW defaults to this mode, even if the MULTIBUS mode is OK. * remove unused sg_err.c * big restructuring : split devinfo.c from main.c. Export : * void basename (char *, char *); * int get_serial (int, char *); * int get_lun_strings (char *, char *, char *, char *); * int get_evpd_wwid(char *, char *); * long get_disk_size (char *); Now we see clearly what is expected from an external package like scsi_id. * stop passing struct env as param --- extras/multipath/ChangeLog | 12 + extras/multipath/Makefile | 4 +- extras/multipath/devinfo.c | 204 ++++++++ extras/multipath/devinfo.h | 19 + extras/multipath/main.c | 255 +++------- extras/multipath/main.h | 9 +- extras/multipath/sg_err.c | 1197 -------------------------------------------- 7 files changed, 313 insertions(+), 1387 deletions(-) create mode 100644 extras/multipath/devinfo.c create mode 100644 extras/multipath/devinfo.h delete mode 100644 extras/multipath/sg_err.c (limited to 'extras/multipath') diff --git a/extras/multipath/ChangeLog b/extras/multipath/ChangeLog index 2cc492a192..31f6c48f69 100644 --- a/extras/multipath/ChangeLog +++ b/extras/multipath/ChangeLog @@ -1,4 +1,16 @@ 2004-02-04 multipath-016 + * add a GROUP_BY_SERIAL flag.
