It's all 64-bit as far as I can tell. I should tell you that I've
installed the xen bits on this "client" system as well.
I installed the open-iscsi bits from the CentOS repository (yum
install iscsi-initiator-utils)
There are three targets set up on my target host, all via the same
portal and port.
whereis says
iscsid: /sbin/iscsid
iscsiadm: /sbin/iscsiadm
rpm says
iscsi-initiator-utils-6.2.0.868-0.7.el5
isicsiadm -m node -P 1 says
Target: iqn.2001-09.net.ketsds:keat.storage.fast1
Portal: 10.1.206.2:3260,1
Iface Name: default
Target: iqn.2001-09.net.ketsds:keat.storage.fast2
Portal: 10.1.206.2:3260,1
Iface Name: default
Target: iqn.2001-09.net.ketsds:keat.storage.fast3
Portal: 10.1.206.2:3260,1
Iface Name: default
Iface Name: default
the third target is the one that I try to attach to...
thanks!
