HP P4500 G2 Email Notification Setup

HI All

We have setup a new SAN network, a data segment and an iscsi segment.

Eg. Data on 192.168.0.0/24 and iSCSI on 10.1.1.0/24

How do we configure to send an email alert from the SAN? We have setup a SMTP server on one of the VMs, and on the same VM we have 2 NICs, one connected to the data switch and the other to the iSCSI switch. Thought it would do the job, but it doesnt appear to be working. Any chance that we need to configure trunking on the 2 switches?

Thanks.

You set it up directly on the SAN.  See page 129 of this: http://h20000.www2.hp.com/bc/docs/support/SupportManual/c02008676/c02008676.pdf

Yes I know how to setup the emails within the SAN, but its not going out as its on a different network segment.

Not sure if you read my 1st post but I need to be able to route out from the iSCSI network to the data network.

Any update?

Has anyone setup email alerts on the SAN (within the iSCSI network), and route email via the LAN network?

Not sure what is the best approach - whether to install RRSA on the server which has 2 NICs, or configure VLAN on the switch or something else?
Can your VM on the iSCSI storage network PING the SAN?

If it can, SMTP delivery should be available to that server, running the SMTP server?

Yes the vm can ping but not the other way. I still can't get it going.

Any update?
So VM can ping the SAN, but the SAN cannot ping the VM?

so there is no connectivity from SAN to VM?

The VM we have has 2 NICs, one on the data network and the other on the SAN network, hence the VM is able to ping the SANs, but not the other way around.

By the way, this is done via VMware, we have 2 vSwitches (data and iscsi).

Firewall is off on the VM.

There's only 2 SAN switches between the SANs and the hosts.

On the VM I can ping the SANs no problems - can ping 2 nodes, and the virtual IP and the iSCSI vSwitches, as they are all on the same IP subnet.

I can ping the NIC with the same IP subnet as the SAN, but not the data network which is on a different subnet.

What do I need to do on the VM to have the 2 NICs to talk to each other?
Okay, it would seem that you need to add a route, or gateway IP Address on the SAN?

use a ntp timesource on your local network.

cant, it wont ping the data network - any other way? the iscsi network is zoned, cant do outbound nor inbound, what is the best method?
Avatar of goraek

ASKER

Yes, they wont be able to see each other unless the ports are trunked and tagged.
can you not, use a NTP server on your management network for the SAN?
Avatar of goraek

ASKER

Nope, all NICs have been used up on the SAN
so all the nics on the SAN are on the iSCSI network, which is your data network.

and you normally manage, by connecting to the iSCSI network?
Avatar of goraek

ASKER

noo... we have 2 dedicated iSCSI switches and 1 data switch - on the host vswitches (iscsi) are connected to the iSCSI switches and so are the SANs, they are dedicated only for iSCSI traffic, hence they are not able to the data network
So your data network is production LAN with servers connected, and this is not connected to SAN.

if this is the case, which is unsual, we always have a storage network, and management network, and SANs are connected to both networks.

if SAN is only connected to iSCSI, you would have to have a router/VLAN layer 3 switch for traffic to route from iSCSI to Data network, to reach NTP server.

or an NTP server dual homed, on both iSCSI and Data network.

ok then.

by the way, why would this be unusual? dont you separate your SAN to your hosts? this setup is recommended by few others including HP unless you have yours setup differently to us

Ok - this will need further planning.
At this stage I've got what I needed.
