Description of problem:
Auto install RHEV-H will success with the follow parameter:
BOOTIF=eth0 storage_init=/dev/mapper/1ATA*9911,/dev/mapper/1ATA*9911 firstboot

so it also should be successful with follow parameter:
BOOTIF=eth0 storage_init=/dev/sda,/dev/sda firstboot

but actually it failed with "storage_init=/dev/sda,/dev/sda" parameter

maybe the root cause happen in the line 73 of the follow code in storage.py
 55         if "OVIRT_INIT" in OVIRT_VARS:
 56             OVIRT_VARS["OVIRT_INIT"] = OVIRT_VARS["OVIRT_INIT"].strip(",")
 57             if "," in OVIRT_VARS["OVIRT_INIT"]:
 58                 disk_count = 0
 59                 init = OVIRT_VARS["OVIRT_INIT"].strip(",").split(",")
 60                 for disk in init:
 61                     skip = False
 62                     if disk_count < 1:
 63                         self.ROOTDRIVE = translate_multipath_device(disk)
 64                         if len(init) == 1:
 65                             self.HOSTVGDRIVE = translate_multipath_device(disk)
 66                         disk_count = disk_count + 1
 67                     else:
 68                         for hostvg in self.HOSTVGDRIVE.split(","):
 69                             if hostvg == disk:
 70                                 skip = True
 71                                 break
 72                         if not skip:
 73                             self.HOSTVGDRIVE += "%s," % disk
 74             else:
 75                 self.ROOTDRIVE = translate_multipath_device(
 76                                     OVIRT_VARS["OVIRT_INIT"])
 77                 self.HOSTVGDRIVE = translate_multipath_device(
 78                                     OVIRT_VARS["OVIRT_INIT"])

changing it into the follow code can resole this issue:

 55         if "OVIRT_INIT" in OVIRT_VARS:
 56             OVIRT_VARS["OVIRT_INIT"] = OVIRT_VARS["OVIRT_INIT"].strip(",")
 57             if "," in OVIRT_VARS["OVIRT_INIT"]:
 58                 disk_count = 0
 59                 init = OVIRT_VARS["OVIRT_INIT"].strip(",").split(",")
 60                 for disk in init:
 61                     skip = False
 62                     translated_disk = translate_multipath_device(disk) 
 63                     if disk_count < 1:
 64                         self.ROOTDRIVE = translated_disk
 65                         if len(init) == 1:
 66                             self.HOSTVGDRIVE = translated_disk
 67                         disk_count = disk_count + 1
 68                     else:
 69                         for hostvg in self.HOSTVGDRIVE.split(","):
 70                             if hostvg == translated_disk:
 71                                 skip = True
 72                                 break
 73                         if not skip:
 74                             self.HOSTVGDRIVE += "%s," % translated_disk
 75             else:
 76                 self.ROOTDRIVE = translate_multipath_device(
 77                                     OVIRT_VARS["OVIRT_INIT"])
 78                 self.HOSTVGDRIVE = translate_multipath_device(
 79                                     OVIRT_VARS["OVIRT_INIT"])



Version-Release number of selected component (if applicable):
rhev-hypervisor6-6.4-20130501.0.el6_4

How reproducible:
100% 
 
Steps to Reproduce:
1.Auto install rhev-h with 
with "BOOTIF=eth0 storage_init=/dev/sda,/dev/sda firstboot" parameter

Actual result:
After Step 1, Auto install RHEV-H failed with "storage_init=/dev/sda,/dev/sda" parameter          
                                                  
Expect result:
Because Auto install RHEV-H will success with "storage_init=/dev/mapper/1ATA*9911,/dev/mapper/1ATA*9911" parameter,
so it also should be successful with "storage_init=/dev/sda,/dev/sda" parameter.
