Re: Problem with iSCSI connected LTO-2 tape drive
I just ran a Wireshark capture on the target system of the iSCSI session for a Windows initiator connecting the tape and then issuing an FSF. I then did the same for the Ubuntu open-iscsi initiator. The capture for the WIndows initiator looks pretty much as I would expect (given my limited knowledge of the iSCSI protocols). The Ubuntu/open-iscsi capture has all sorts of odd stuff like logins being sent to the target every 15 seconds whle the FSF is being processed. Definitely borked I think. Do any of the open-iscsi folk watch this forum or am I talking to myself? Dave On Sunday, December 11, 2016 at 11:55:15 AM UTC, Dave partridge wrote: > > Ubuntu 16.04.1 LTS with kernel 4.8.13.

Ubuntu 16.04.1 LTS with kernel 4.8.13. Connected to target drive over 1GB ethernet. Drive is HP Ultrium 460 (Ultrium 2), firmware is F63D - which is latest).

Problem with iSCSI connected LTO-2 tape drive
I did: root@Charon:/home/amonra# mt -f /dev/st0 fsf 1 mt: /dev/st0: rmtioctl failed: Input/output error root @Charon:/home/amonra# The rmtioctl message appeared after about 10-15 seconds, and the iSCSI target showed that the session had dropped after another 10-15 seconds. When I was returned to the command line prompt, the target showed the session as connected again. During most/all of this time the forward space file operation was still running. root@Charon:/home/amonra# iscsiadm -m node --targetname "iqn.2008-08.com.starwindsoftware:mercury-ultrium2" --portal "192.168.129.77:3260" # BEGIN RECORD 2.0-873 node.name = iqn.2008-08.com.starwindsoftware:mercury-ultrium2 node.tpgt = -1 node.startup = manual node.leading_login = No iface.hwaddress = iface.ipaddress = iface.iscsi_ifacename = default iface.net_ifacename = iface.transport_name = tcp iface.initiatorname = iface.bootproto = iface.subnet_mask = iface.gateway = iface.ipv6_autocfg = iface.linklocal_autocfg = iface.router_autocfg = iface.ipv6_linklocal = iface.ipv6_router = iface.state = iface.vlan_id = 0 iface.vlan_priority = 0 iface.vlan_state = iface.iface_num = 0 iface.mtu = 0 iface.port = 0node.discovery_address = 192.168.129.77 node.discovery_port = 3260 node.discovery_type = send_targets node.session.initial_cmdsn = 0 node.session.initial_login_retry_max = 8 node.session.xmit_thread_priority = -20 node.session.cmds_max = 128 node.session.queue_depth = 32 node.session.nr_sessions = 1 node.session.auth.authmethod = None node.session.auth.username = node.session.auth.password = node.session.auth.username_in = node.session.auth.password_in = node.session.timeo.replacement_timeout = 120 node.session.err_timeo.abort_timeout = 15 node.session.err_timeo.lu_reset_timeout = 30 node.session.err_timeo.tgt_reset_timeout = 30 node.session.err_timeo.host_reset_timeout = 60 node.session.iscsi.FastAbort = Yes node.session.iscsi.InitialR2T = No node.session.iscsi.ImmediateData = Yes node.session.iscsi.FirstBurstLength = 262144 node.session.iscsi.MaxBurstLength = 16776192 node.session.iscsi.DefaultTime2Retain = 0 node.session.iscsi.DefaultTime2Wait = 2 node.session.iscsi.MaxConnections = 1 node.session.iscsi.MaxOutstandingR2T = 1 node.session.iscsi.ERL = 0 node.conn[0].address = 192.168.129.77 node.conn[0].port = 3260 node.conn[0].startup = manual node.conn[0].tcp.window_size = 524288 node.conn[0].tcp.type_of_service = 0 node.conn[0].timeo.logout_timeout = 15 node.conn[0].timeo.login_timeout = 15 node.conn[0].timeo.auth_timeout = 45 node.conn[0].timeo.noop_out_interval = 5 node.conn[0].timeo.noop_out_timeout = 5 node.conn[0].iscsi.MaxXmitDataSegmentLength = 0 node.conn[0].iscsi.MaxRecvDataSegmentLength = 262144 node.conn[0].iscsi.HeaderDigest = None node.conn[0].iscsi.DataDigest = NoneThe return to the command prompt took a while longer. node.conn[0].iscsi.IFMarker = No node.conn[0].iscsi.OFMarker = No # END RECORD root@Charon:/home/amonra# I'm guessing that the problem relates to iSCSI timeouts for tape devices.
