Red Hat Bugzilla – Bug 1277262
iscsi target broken with ms iscsi initiator in recent kernels
Last modified: 2015-11-02 15:36:49 EST
Description of problem:
Upgraded my fedora 22 installation from kernel 4.0.4-303.fc22.x86_64 to 4.2.3-200.fc22.x86_64 and now iscsi target no longer works.
i have a windows computer that uses the microsoft iscsi initiator and this worked just fine on my 4.0.4 kernel but with 4.2.3 i get the following errors in dmesg:
Got unknown iSCSI OpCode: 0x43
Cannot recover from unknown opcode while ERL=0, closing iSCSI connection.
repeatedly when ms iscsi intiator tries to connect and then the connection fails resulting in unavailable isci devices.
after a bit of searching i found the following discussion that i think describes the issue very well:
looks like there is a kernel bug.
setup targetcli on linux and use a windows computer as iscsi initiator.
with older kernels like 4.0.4 it works, but with newer 4.2.3 kernel initiator is unable to connect.
not possible to connect
connection should work as it did with older kernels.
