203 hava a iSCSI target named poolA that I am trying to log into using this command:

iscsiadm -m node -T poolA -p -l

I am trying to use it as a vg. Secondly, I create two lvs on this vg, and lastly, I logout:

iscsiadm -m node -T poolA -p -u

After I execute lvs, the following error occurs:

/dev/dm-2: read failed after 0 of 4096 at 0: Input/output error
/dev/dm-5: read failed after 0 of 4096 at 0: Input/output error

Can I get around this error without a reboot? Thanks!
