kernel component, BZ#1170328
When the Internet Small Computer System Interface (iSCSI) target is set up using the iSCSI Extensions for RDMA (iSER) interface, an attempt to run a discovery over iSER fails. Consequently, in some cases, the target panics. Users are advised to not use iSER for discovery but use iSER only for the login phase.
kernel component, BZ#1185396
When using the server as an iSER-enabled iSCSI target and connection losses occur repeatedly, the target can stop responding. Consequently, the kernel becomes unresponsive. To work around this issue, minimize iSER connection losses or revert to non-iSER iSCSI mode.
kernel component, BZ#1061871, BZ#1201247
When a storage array returns a CHECK CONDITION status but the sense data is invalid, the Small Computer Systems Interface (SCSI) mid-layer code retries the I/O operation. If subsequent I/O operations receive the same result, I/O operations are retried indefinitely. For this bug, no workaround is currently available.
