Where is the target IP in the libstoragemgmt model?
by nabl＠hush.com
Hi,
I've been looking at libstoragemgmt and have a question and an
observation (please let me know if this is not the appropriate
forum):
Question:
Looking at the documentation, I see the method by which an initiator
IQN is given permission to access a volume, but not the details of
how the iSCSI session is actually established.
For example, I expect to do something like
sudo iscsiadm -m discovery -t sendtargets -p $IP
where $IP is the IP of the machine with the volume (perhaps there is
more than one IP if it is connected over several networks), and then
see the volume I want show up in the resulting list.
But what I don't see in the libstoragemgmt model is where such an IP
(or list of IPs) might be found, e.g., the System object in the model
seems to have only id, name, and status.
Is the user expected to just know the target IP(s)?
Observation:
Has anyone installed libstoragemgmt on Ubuntu?
I have Ubuntu 12.04.5 LTS and installed libstoragemgmt just to try
out sim:// following the instructions at
http://libstorage.github.io/libstoragemgmt-doc/doc/install.html#1.2.-comp...
I succeeded in installing, though I had to
./configure --without-rest-api
because in my case
Requested 'libmicrohttpd >= 0.9' but version of libmicrohttpd is
0.4.6
When I tried to run lsmd it exited with 1 and I saw in
/var/log/syslog:
lsmd: Unable to access socket directory /var/run/lsm/ipc, errno= 13
I got rid of that error by doing
sudo mkdir -p /var/run/lsm/ipc
then lsmd -v returned 0 (echo $?), although in /var/log/syslog I saw
lsmd: Warn: Missing libstoragemgmt user, running as existing user!
lsmd: Scanning plug-in directory /usr/bin
lsmd: No plugins found in directory /usr/bin
and
lsmcli -u 'sim://' list --type systems
still produced
DAEMON_NOT_RUNNING(12): The libStorageMgmt daemon is not running
(process name lsmd), try 'service libstoragemgmt start'
Given the exit code of 0 and the fact that plugins were presumably
optional, I was a bit confused. I did figure out that plugins are
not after all optional and did
lsmd -v --plugindir ./libstoragemgmt-1.2.3/plugin
but I think the installation documentation at
http://libstorage.github.io/libstoragemgmt-doc/doc/install.html
could be improved here with the additional step required for those
installing from source.
Thanks,
Michael

Thanks to all those that helped make this release better by submitting

appreciated!
Giving it a try:

*Warning/disclaimer*
This library has the ability to destroy any and all data on a storage
controller (either from user error or because of a code bug in the
library itself). I would suggest using and developing on
only non-production storage arrays which have no data of value or
utilizing the simulator while developing with the library.
As always any feedback and improvements are welcomed.
Best regards!
