FAQ
ISCSI client
iscsi_discovery 192.168.100.32
List connected targets
iscsiadm -m session
which seems to list only one, for multiple:
tgtadm --lld iscsi --op show --mode conn --tid 1
but that needs more work
List targets
iscsiadm -m discovery -t sendtargets -p 192.168.100.32
Connect to target
iscsiadm -m node --targetname="iqn.2018-5.mynet:drbd0" --portal "192.168.100.32" --login
if you get things like "iscsiadm: No records found" try a thing like
iscsiadm --mode node -l all
Disconnect from target
iscsiadm -m node -T iqn.2018-5.mynet:drbd0 -p 192.168.100.32 -u
Show new size of target
iscsiadm -m node --targetname="foo.bar" -R
Disconnect all targets
iscsiadm --mode node -u all
On server
list targets
tgtadm --lld iscsi --mode target --op show
list connected targets
tgtadm --lld iscsi --mode conn --op show --tid 1
And disconnect target:
tgtadm --lld iscsi --op delete --mode conn --tid 1 --sid 2 --cid 0
Reload tgtd configuration
tgt-admin --update ALL
or
tgt-admin --update your.irqn.string
Show tgdt config
tgt-admin --dump
The disk contains an unclean file system (0, 0).
Metadata kept in Windows cache, refused to mount. Falling back to read-only mount because the NTFS partition is in an unsafe state. Please resume and shutdown Windows fully (no hibernation or fast restarting.)

On ESXi

Error messages
