targetcli/> ls/> iscsi/iqn.2003-01.org.linux-iscsi.ip-10-0-1-10.x8664:sn.a3776832068c/tpg1/ get auth- Review initiator configuration.
View existing block devices:
lsblkVerify network connectivity to the target:
telnet 10.0.1.10 3260Review the initiator configuration file:
vim /etc/iscsi/iscsid.confComment out the authentication settings:
#node.session.auth.authmethod = CHAP ... #node.session.auth.username = server2 #node.session.auth.password = secretCheck for existing target records:
iscsiadm -m nodeVerify the name in
/etc/iscsi/initatorname.iscsimatches the target ACL:cat /etc/iscsi/initiatorname.iscsiRetrieve the target from Server1:
iscsiadm -m discovery -t sendtargets -p 10.0.1.10Connect to the target:
iscsiadm -m node -T iqn.2003-01.org.linux-iscsi.ip-10-0-1-10.x8664:sn.a3776832068c -lVerify the block device is available:
