VMware ESX: unable to get host info

[Marco MM]

Infrastructure:
- On one ESX 3.01 I installed HP Management Agents for VMware 3.x 7.7.0.
- I have also a central HP SIM 5.1 (mgmt_IP).

Configuration:
- Edited on the ESX the file /etc/snmp/snmpd.conf in this way:
rocommunity myreadcomm 127.0.0.1
rocommunity myreadcomm mgmt_IP
trapsink snmphp.it.infores.com public

- mgmp_IP is resolved correctly
- from mgmt_IP I can do an snmpquery using commmunity "myreadcom" (with an snmp-query software to test results)
- I can remotely connect to HP Management Console on ESX and see the homepage and all features (I can telnet to port 2381 on ESX - so firewall port on ESX is open)
- HP System management Homepage on ESX is configured, in security, "trust mode" to "trust all"
- mgmt_IP receive trap from ESX (for instance when I restart the snmp service on the ESX an entry "cold start" in HPSIM is generated)
- I configured HP SIM to ping using TCP on an particular TCP port (xxxx) and it works (so firewall port on ESX is open)

All seems to work fine but when I try to discover my ESX from HP SIM (to gather ESX dataand import it into the HPSIM infrastructure) it fails with this error:
"Data collection was skipped for this system because it is suspended or inaccessible.
Root Cause: The target system has been suspended or somehow become inaccessible.
Corrective Action: Check system status and reset (if appropriate) the following System Page: Suspend/Resume Monitoring."

Can someone help me?

Thanks in advance.

Check what protocols have been discovered, click on server name look under the Product Description.
You should see items like:
HTTP:0.0, SMH:2.0, SNMP:1.0, SSH:SSH-2.0-OpenSSH_3.6.1p2
If you've made changes to snmp, try rerunning an identification task.

In my snmpd.conf file, I use the FQDN of the vmhost server. Not sure if that would make a difference.

Test browsing to the SMH from the HPSIM server.

Under the Product Description I can only see "Unmanaged"

Rerunning an identification task do not solve the problem

Not sure what do you mean with "In my snmpd.conf file, I use the FQDN of the vmhost server." snmpd.conf is on the vmhost so maybe you add in it the HPSIM FQDN.

SMH from the HPSIM server works well.

I have news, not really good news:
magically, during the week-end, one server (another continue to not work) has been visible for HP SIM for sometimes in fact HP SIM could import it and collect all data.
I saw it in the morning and in the same time I tried to connect to SMH of the ESX...without success! the SMH stopped working!! I stopped snmpd, hpasm, delete the RW community line into snmpd.conf, start snmpd and hpasm and try to collect ESX data from SIM: IT WORKS!!! and now it continues to work...but don't know why! In fact I replicated the same settings (settings I tried many time before but without success...what is changed...maybe the weather!!) on the other ESX and it continue to not work.

I lost any hope now Really frustrated for HP agents for VMware and SIM product!
