From 7f4954d04026f28b0ebe65a514f06fefad8efaca Mon Sep 17 00:00:00 2001 From: David Zeuthen <davidz@redhat.com> Date: Fri, 4 Dec 2009 11:25:09 -0500 Subject: Export ID_WWN_VENDOR_EXTENSION and ID_WWN_WITH_EXTENSION Some SCSI devices use the same WWN and have a WWN extension that we need to take into account when creating the /dev/disk/by-id/wwn symlinks. Thus, introduce ID_WWN_WITH_EXTENSION. This property will contain either the WWN (if no extension is present) or the WWN with the vendor extension appended. Example: # /lib/udev/ata_id/ata_id --export /dev/sda |grep WWN ID_WWN=0x5001517387d61905 ID_WWN_WITH_EXTENSION=0x5001517387d61905 # /lib/udev/scsi_id --whitelisted --export -d /dev/sdb |grep WWN ID_WWN=0x600508b400105df7 ID_WWN_VENDOR_EXTENSION=0x0000e00000d80000 ID_WWN_WITH_EXTENSION=0x600508b400105df70000e00000d80000 # /lib/udev/scsi_id --whitelisted --export -d /dev/sdc |grep WWN ID_WWN=0x600508b400105df7 ID_WWN_VENDOR_EXTENSION=0x0000e00000db0000 ID_WWN_WITH_EXTENSION=0x600508b400105df70000e00000db0000 Signed-off-by: David Zeuthen <davidz@redhat.com> --- rules/rules.d/60-persistent-storage.rules | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'rules/rules.d') diff --git a/rules/rules.d/60-persistent-storage.rules b/rules/rules.d/60-persistent-storage.rules index c839f3bc06..89041a950b 100644 --- a/rules/rules.d/60-persistent-storage.rules +++ b/rules/rules.d/60-persistent-storage.rules @@ -67,7 +67,7 @@ ENV{ID_FS_USAGE}=="filesystem|other|crypto", ENV{ID_FS_UUID_ENC}=="?*", SYMLINK+ ENV{ID_FS_USAGE}=="filesystem|other", ENV{ID_FS_LABEL_ENC}=="?*", SYMLINK+="disk/by-label/$env{ID_FS_LABEL_ENC}" # by-id (World Wide Name) -ENV{DEVTYPE}=="disk", ENV{ID_WWN}=="?*", SYMLINK+="disk/by-id/wwn-$env{ID_WWN}" -ENV{DEVTYPE}=="partition", ENV{ID_WWN}=="?*", SYMLINK+="disk/by-id/wwn-$env{ID_WWN}-part%n" +ENV{DEVTYPE}=="disk", ENV{ID_WWN_WITH_EXTENSION}=="?*", SYMLINK+="disk/by-id/wwn-$env{ID_WWN_WITH_EXTENSION}" +ENV{DEVTYPE}=="partition", ENV{ID_WWN_WITH_EXTENSION}=="?*", SYMLINK+="disk/by-id/wwn-$env{ID_WWN_WITH_EXTENSION}-part%n" LABEL="persistent_storage_end" -- cgit v1.2.3-54-g00ecf
