Hi, everyone:
I'd like to ask a question on setting rhas4 support multiple luns. The details
are as the following:
The platform is RH AS4 (Linux 2.6.9-42.ELsmp #1 SMP Wed Jul 12 23:27:17 EDT
2006 i686 i686 i386 GNU/Linux). And the iscsi rpm packages installed are
iscsi-initiator-utils-4 (See http://ils-4.ora-code.com).0.3.0-5
iscsi-initiator-utils-debuginfo-4 (See http://nfo-4.ora-code.com).0.3.0-5
Then, I'd like to install Bakbone backup server and a QUANTUM virtual
library with Model DX3000 through iSCSI connected. I have set the iscsi.conf
as the below:
DiscoveryAddress=172.16.1.17
OutgoingUsername=test
OutgoingPassword=abcdef123456
LUNs=0-255
While I started iscsi service at rhas4 server, the messages log file is as
the below:
Oct 10 09:29:29 backup2 iscsi: iscsi config check succeeded
Oct 10 09:29:29 backup2 kernel: iscsi-sfnet: Loading iscsi_sfnet version 4:0.1

Oct 10 09:29:34 backup2 iscsi: iscsid startup succeeded

Oct 10 09:29:34 backup2 kernel: Type: Medium Changer
ANSI SCSI revision: 02
Oct 10 09:29:34 backup2 kernel: Attached scsi generic sg2 at scsi15, channel 0

Oct 10 09:29:34 backup2 scsi.agent[3115]: changer at /devices/platform/host15
/target15:0:0/15:0:0:0
Now the server can only know the library ,not the drivers included in the
library. I suppose maybe the rhas4 or iscsi service not support multiple luns.
And I also have known the wrong parameter luns=0-255 in iscsi.conf.
But how do I set to make the server support multiple luns and know both
library and drivers it including?
Many thanks.
