  • 1. Issue: Unable to start iSCSI service on Redhat Enterprise Linux 6. Symptoms: After installing iSCSI modules using 'yum install iSCSI*', following modules were installed by the system. [root@redhatcentos Desktop]# rpm -qa | grep iscsi iscsi-initiator-utils-6.2.0.873-2.el6.x86_64 iscsi-initiator-utils-devel-6.2.0.873-2.el6.x86_64 But, when trying to start the iscsi service, iscsi service remained stopped, as shown in the example below. [root@redhatcentos Desktop]# service iscsid status iscsid is stopped [root@redhatcentos Desktop]# service iscsid start [root@redhatcentos Desktop]# service iscsid status iscsid is stopped # Even though service 'start' command was issued, iscsid remained stopped.
  • 2. Cause: In Red Hat Enterprise Linux 6, the iSCSI service is lazily started by default. If root is not on an iSCSI device or there are no nodes marked with node.startup = automatic then the iSCSI service will not start. Ref: https://access.redhat.com/site/documentation/enUS/Red_Hat_Enterprise_Linux/6/html/Storage_Administration_Guide/chiscsi.html Resolution: Use iscsiadm command that requires iscsid or the iscsi kernel modules to be started. For example, running the discovery command iscsiadm -m discovery -t st -p ip:port will cause iscsiadmin to start the iSCSI service. [root@redhatcentos Desktop]# iscsiadm -m discovery -t sendtargets -p 192.168.1.12 Starting iscsid: [ OK ] 192.168.1.12:3260,2 iqn.1992-08.com.netapp:sn.4055372815 [root@redhatcentos Desktop]# service iscsid status iscsid (pid 3039) is running... [root@redhatcentos Desktop]# Or, Force the iSCSI daemon to run and iSCSI kernel modules to load, run service iscsid force-start. ashwinwriter@gmail.com
