Core-iSCSI

Configuration

• Get the versions of the modules and user space code (where applicable).
• Get the information in the configuration files for Core-iSCSI & the Core-iSCSI tools:
  • /etc/sysconfig/initiator
  • /etc/sysconfig/iscsi_device_maps
  • /etc/sysconfig/initiator_auth

Logs

• If the system is having non-fatal isses with iSCSI (i.e.: the module can be unloaded), then get the output from /var/log/messages:

klogd

• If the system is locking or crashing, get the output from the console via the serial console.
• Where possible, collect iSCSI network traffic with Wireshark or Ethereal.

Debugging output

Enable debugging output for Core-iSCSI:

DEBUG_ISCSI = 1 core-iscsi-vx.x.x.x/MCONFIG

If the resulting verbosity is insufficient, recompile Core-iSCSI:

1. Enable additional debugging sections in iscsi_debug.h
2. Compile, shutdown, install and restart to enable the changes
