CentOS - Feb 2011 - working with multiple password protected iSCSI targets on one host

Hi,

How do I setup multiple password protected iSCSI targets on Linux?

I know that mounting a password protected iSCSI target requires modify
these records with the appropriate values:


node.session.auth.username = My_ISCSI_USR_NAME
node.session.auth.password = MyPassword
discovery.sendtargets.auth.username = My_ISCSI_USR_NAME
discovery.sendtargets.auth.password = MyPassword


But, now I need to mount another iSCSI target, from a different SAN
that has a different username & password than whan I have configured
here for the one already mounted.

How do I tell iscsiadm which CHAP settings to use with which iSCSI target?

I think there is not elegant way to do this.. I follow those steps:

1) Set discovery.sendtargets.{auth,password} in iscsid.conf for target-1 
+ restart iscsid service.

2) Set CHAP settings for target-1 + connect:

# iscsiadm -m node --targetname ${TARGETNAME1} -p ${PORTAL1} -o update 
-n node.session.auth.username -v ${USERNAME}
# iscsiadm -m node --targetname ${TARGETNAME1} -p ${PORTAL1} -o update 
-n node.session.auth.password -v ${PASSWORD}
# iscsiadm -m node --targetname ${TARGETNAME1} -p ${PORTAL1} -l

3) Disconnect from target-1:

# iscsiadm -m node --logoutall all

4) Set discovery.sendtargets.{auth,password} in iscsid.conf for target-2 
+ restart iscsid service.

5) Set CHAP settings for target-2 + connect:

# iscsiadm -m node --targetname ${TARGETNAME2} -p ${PORTAL2} -o update 
-n node.session.auth.username -v ${USERNAME}
# iscsiadm -m node --targetname ${TARGETNAME2} -p ${PORTAL2} -o update 
-n node.session.auth.password -v ${PASSWORD}
# iscsiadm -m node --targetname ${TARGETNAME2} -p ${PORTAL2} -l

It works! Now you can login/logout in both iSCSI targets:

# iscsiadm -m node --logoutall all
# iscsiadm -m node --loginall all

Cheers,
