Description of problem:

In the script mkinitrd, the variable rootdev is overwritten when the multipath
is activated that leads to have the wrong rootdev to create the line  "mkrootdev
-t ext3 -o defaults,ro /dev/sdc" instead of mkrootdev -t ext3 -o defaults,ro
/dev/VolGroup00/LogVol01"

In the mkinitrd line 1135

       if [ "${withmpath}" -eq "1" ]; then
           for rootdev in ${rootdevs} ; do     <==  Overwrite the rootdev variable
               disk=$(find_dm_in_sysblock ${rootdev} | sed -e 's,^/sys,,') 
               wwid=$(/sbin/scsi_id -g -u -s ${disk})
               if [ -z "${wwid}" ]; then
                   # Could be EMC unit requiring special option
                   wwid=$(/sbin/scsi_id -g -ppre-spc3-83 -u -s ${disk})
               fi
               if [ -n "${wwid}" ]; then
                   case " ${root_wwids} " in
                       *" ${wwid} "*) continue ;;
                       *) root_wwids="${root_wwids} ${wwid}" ;;
                   esac
               fi
           done
           if [ -n "$root_wwids" ]; then
               use_multipath=1
           fi
       fi


Version-Release number of selected component (if applicable):

mkinitrd-5.1.19.6-28

How reproducible:

when multipath is activated for boot on SAN

Steps to Reproduce:
1.

~/mkinitrd -f initrd-2.6.18-92.1.6.el5.img 2.6.18-92.1.6.el5
  
Actual results:
The system can't boot with the initrd generated by this script

Expected results:

Boot the system on SAN with the correct initrd

Additional info:

In the mkinitrd line 1135
rename the variable rootdev by rootdev1 in the following line solve this problem

       if [ "${withmpath}" -eq "1" ]; then
           for rootdev1 in ${rootdevs} ; do     <==  Overwrite the rootdev variable
               disk=$(find_dm_in_sysblock ${rootdev1} | sed -e 's,^/sys,,') 
               wwid=$(/sbin/scsi_id -g -u -s ${disk})
               if [ -z "${wwid}" ]; then
                   # Could be EMC unit requiring special option
