You can set specific paths to not get logged into automatically by doing iscsiadm -m node -T target -p ip -o update -n node.startup -v manual Thanks! Now more complicated. Can I blacklist specific devices? My array is limited only to 4 initiator-storage poll mappings (which are used to allow access to logical disk X only from initiator A). Unfortunately I have 5 hosts. So I have 5 logical partitions on array (X, Y, Z, Q, W) and 5 hosts (hA, hB, hC, hD, hE). hA has access to X only, hB to Y only, hC to Z only but hD and hE have access to both, Q and W. (Q meant for host hD, W meant for host hE). Totall 4 host -- storages mapping in use. I need some way to prevent host hD from accessing storage W and prevent host hE from accessing storage Q. Os level would be enough. This is only to disallow silly mistakes made by admin. Is there a way on open-iscsi level to make host hD not see (or ignore) storage device W? Some other, kernel level, way would be enough, too. Simplest what comes to my mind is simply rm /dev/sdX where sdX are devices to the other host storage. -- You received this message because you are subscribed to the Google Groups open-iscsi group.

blacklisting some paths in multipath environment
Hello, I'm trying to use open-iscsi with DS3300 array. DS has two controllers, each 2 ethernet ports. Unfortunately I use some SATA disk that aren't capable to be connected into two controllers (only one path on the SATA connector). This causes disks to be accessible only through one controller. My Linux system unfortunately still sees all 4 paths (two controllers x 2 eth ports each; target has 4 IPs then). How I can blacklist some paths and still use automatic node.startup?
