This request was evaluated by Red Hat Product Management for inclusion, but this component is not scheduled to be updated in the current Red Hat Enterprise Linux release. If you would like this request to be reviewed for the next minor release, ask your support representative to set the next rhel-x.y flag to "?". |
Description of problem: On a system with CCISS controllers there are no /dev/disk/by-id/* nodes fore the /dev/cciss/c*d* devices. Only the per partition UUID symlinks are being created. Usage of the symlinks is however recommended for setting up the raw devices in the installation documentation of a certain database software... Version-Release number of selected component (if applicable): udev-095-14.21.el5 How reproducible: always Steps to Reproduce: 1. Boot a system with logical disks on CCISS controller 2. ls -l /dev/disk/by-id Actual results: ls: /dev/disk/by-id/: No such file or directory Expected results: Something like total 0 lrwxrwxrwx 1 root root 16 May 22 10:48 cciss-3600508b1001fffffa00f232e41ca9403 -> ../../cciss/c0d0 lrwxrwxrwx 1 root root 16 May 22 10:48 cciss-3600508b1001fffffa00f34e649379404 -> ../../cciss/c0d1 Additional info: Since there has been the "-n" option added in the recent release, we should make an use of it in the udev rules. Adding the following line to /etc/udev/rules.d/50-udev.rules seems to fix the issue: KERNEL=="cciss?c[0-9]d[0-9]", ENV{ID_SERIAL}=="", ENV{ID_BUS}="cciss", IMPORT{program}="scsi_id -g -x -n -a -s %p", SYMLINK+="disk/by-id/$env{ID_BUS}-$env{ID_SERIAL}"
