esxi server fails to connect to iSCSI on a different network / can ping..

[TryllZ]

Hi,

I have a lab setup on workstation where I have 2 clusters: Mgmt_Compute and Mgmt_Infrastructure.

Mgmt_Compute is on 192.168.105.0/24 network and has esxicomp1 and esxicomp2 esxi servers.

Mgmt_Infrastructure is on 192.168.100.0/24 network and has esxi1, esxi2, and esxi3 esxi servers.

A Firewall is configured and all devices can ping each other, and can be seen below device device esxicomp2 can ping its own gateway 192.168.105.3, and the DNS server 192.168.100.10 which is also the iSCSI storage server.

However when I configure iSCSI through vCenter the esxicomp1 and esxicomp2 do not connect to the iSCSI storage as can be seen below.

esxi1 showing as connected.

Any specific reason for this or am I missing something.

And if it matters I have 1 DVSwitch with 1 Uplink and 2 portgroups, MgmtA which has esxi1, 2, and 3, and MgmtB which has esxicomp1 and esxicomp2.

Thanks..

1. If you wanna ping than use vmkping from command line and think about MTU and selecting the right outgoing VMK/NIC as well
2. Some storages have a protection that only the first host can connecting unless you tick the box for multiple host connections
3. Storage ACL needs to cover both Hosts
4. Investigate  vmkernel.log instead looking the the GUI where nothing is shown

Joerg

Hi Joerg,

Thanks for pointing out all those out.

I have done a vmkping from the esxi and they result in success.

[root@esxicomp2:~] vmkping 192.168.100.10

PING 192.168.100.10 (192.168.100.10): 56 data bytes

round-trip min/avg/max = 0.851/1.443/2.032 ms

As for points 2 and 3 I'll go through the settings of the iSCSI, and will go through the vmkernel.log as well.

Thanks again.

So I went through the logs and there is only 1 mentioning of the iSCSI adapter (highlighted in red below), nothing else.

do a vmkping with specifying the vmkernel-Port on which you do iscsi: vmkping -I vmkX 192.168.100.10

is the firewall-config correct ? port 3260 open ?

[TryllZ]

Hi bewe,

The ping is successful with the vmk0 as it is the only vmk on the esxi server.

[root@esxicomp1:~] vmkping -I vmk0 192.168.100.10

The firewall config is the same for all networks, no special configuration was done, I still opened port 3260 on the firewall and tried again, did not work.

Thanks..

Firewall on esxi for Software iSCSI is also open ? iSCSI-discovery setup properly ?

do an vmkiscsi-tool -T vmhba65 on the host and see the output

[TryllZ]

Firewall on esxi for iSCSI is open.

As for iSCSI-Discovery is set for Dynamic Discovery.

While the command has no output.

[root@esxicomp1:~] vmkiscsi-tool -T vmhba65

No active targets.

And just to confirm because iSCSI settings on all servers are same, I just added esxi1 server and it adds iSCSI properly.

[root@esxi1:~] vmkiscsi-tool -T vmhba65

------ Target [iqn.1991-05.com.microsoft:vserver-esxihosts-target] info ------

Thanks again, appreciate the help..

[berndweyand]

what does vmkiscsi-tool -D vmhba65 say ?

but in my opinion you should search the problem at the storage

[TryllZ]

For the command I get..

[root@esxicomp1:~] vmkiscsi-tool -D vmhba65

=========Discovery Properties for Adapter vmhba65=========

iSnsDiscoverySettable    : 0

iSnsDiscoveryEnabled     : 0

slpDiscoverySettable  : 0

DISCOVERY ADDRESS          : 192.168.100.10

No Static Discovery Targets Found

I'm looking into the storage for any issues..

[berndweyand]

you can test from the esxi if the port on the storage server can be reached:

nc -z 192.168.100.10 3260

[TryllZ · Accepted solution]

Apologies for the delayed reply, got caught in work.

The issue was the port binding, the esxicomp1 did not have its port binding done.

After the port binding the iSCSI disk is now showing connected.

Thanks a lot, appreciate everyone's time.
