Description

Hi,

I have defined a BLOCK datastore:

<DATASTORE>
  <ID>104</ID>
  <UID>0</UID>
  <GID>0</GID>
  <UNAME>oneadmin</UNAME>
  <GNAME>oneadmin</GNAME>

    <TM_MAD><![CDATA[dev]]></TM_MAD>
    <TYPE><![CDATA[IMAGE_DS]]></TYPE>
  </TEMPLATE>
</DATASTORE>

Then I have defined an image
<IMAGE>
  <ID>11</ID>

  <DISK_TYPE>2</DISK_TYPE>

</IMAGE>

On instantiate, the link is not correct:

datastores/100/17/disk.2 -> 01:00.2-ip-172.16.2.150:3260-iscsi-iqn.2001-05.com.equallogic:0-1cb196-aa15f4557-17d0059e1bf58e8b-b2-mgmt-backup-cb-sftp-data-lun-0

"/dev/disk/by-path/pci-0000:" is missing.

I have not found why yet ...

Regards,
Nicolas.
