[linux-iscsi-users] Discovery Optional?

[Luis P C. <lp...@ra...>]

It seems that there are cases were discovery is
not needed and not wanted.  Can it be optional?

It would be nice if discovery were optional so
that one could add the iscsi node's IP address
to the target name section, something like:

/etc/iscsi.conf:

TargetName=iqn.xxx.yyy:zzz
 TargetAddress=10.1.1.100:3260
 Username=bob
 Password=xxxx
 LUNs=20-24
 InitialR2T=yes

I understand this is not possible right now with the
scsi.conf file but I know it can be done with the
ISCSI_ESTABLISH_SESSION ioctl.  That's what the
'init' program does in the Linux mkinitrd for iscsi
boot.  I also know that one can simulate this using the
'Enable' entry in the config file.

However, when one wants to configure an initiator
to connect to specific targets, discovery seems to
get in the way because the 'DiscoveryAdress' entry
may or may not be shared by the targets.  Therefore,
everytime we remove a target from the config file,
we need to figure out if the discovery address
used to find that target is also used by another target
so we don't leave that other target without its
discovery address.

If the iscsi target node address info were with the
target, then one can simply remove the target config
from the file without worrying about affecting
a different target.

Any hints that could help us eliminate this problem?

Thanks in advance for your help.
