Homologationt Multi-I/O Card Sans and Multipathing

[FabianCohen1]

In the system Management Hewllet Packard SMH using the SNMP Agents in public class versión assign SNMP and WBEM.  To quickly determine if there are any hardware issue. In the network the class snmp monitoring indicate lost connectiont network . In the homologationt of High Availability tacnologyc procedure generate rebundace. But the lost lun asignned bethen storage and HBA indicate incorrect procedure. 

The server is in cluster and availability for services, but in the process to homologation in network indicate the value 

Main

Pair Frequency (MHz) Status Value (dB) Limit (dB) Margin (dB) 1,2-3,6 243.000 Pass 40.3 35.5 4.8 1,2-4,5 237.000 Fail* 35.5 35.7 -0.2 1,2-7,8 249.500 Pass 45.2 35.4 9.8 3,6-4,5 234.000 Fail 31.0 35.8 -4.8 3,6-7,8 213.000 Pass 39.5 36.5 3.0 4,5-7,8 43.500 Pass 53.0 47.7 5.3

What best practice indicate to certified and homologate of network Multi-I/O and  HBA for waranty services?

Hello!

The scenario you're outlining relates to homologating multi-I/O cards, configuring multipathing, and ensuring network redundancy, with SNMP and WBEM agents being used for system health checks. The emphasis appears to be on maintaining high availability (HA) while troubleshooting connectivity problems between storage (LUNs) and host bus adapters (HBAs). Key details from your explanation include SNMP monitoring flagging lost network connections, storage paths showing failures, and homologation results revealing a mix of pass/fail outcomes for frequency values.

Can you check this and let me know: 

- Check out all paths are correctly configured to provide failover support. Tools like HPE's Storage Multipathing (MPIO) or Device Mapper Multipath (DM-Multipath) should be configured to handle I/O traffic across multiple paths.

-Investigate the failed paths in your cluster. SNMP agents showing lost connections might indicate a path failure. Use storage management tools to identify whether the failure is on the storage end, the HBA, or the SAN switch.

Let me know if you still have any issues

Hello how are you?

But in your indicationt exists develop open source example nagios and agent in snmp comunity public class provocate risk and vulnerability  HBA brodcast. 

The Hewllet Packard provide Hewllet Packard Power Advisor for monitoring, but in snmp agent and certificate of CA de brodcast provocate in Legacy HBA Hardware Address interruptiont incorrect. The comunicationt private in agent SNMP and Power Advisor , not is class public and not is for all network. 

The package lost is large type provocate error. 

How homologate network in develop to power Advisor monioring agent to HBA 

Thanks and best regards

[Mr_Techie]

Am good, thanks. 

Below are some steps to properly homologate your network for Power Advisor monitoring with HBAs, while addressing your concerns about security and network errors:

- Try upgrade to SNMP3 and configure SNMP to limit its traffic to specific IP ranges, isolating SNMP communication to the trusted management network and Power Advisor servers.

-Separate your monitoring and management traffic from regular network traffic. Use VLANs or a dedicated management network to ensure that SNMP and Power Advisor communication remain private. And apply strict firewall rules to limit SNMP agent and Power Advisor traffic only to authorized systems. 

-Update HBA Firmware too latest version if not updated. 

-When configuring HPE Power Advisor, check it’s properly integrated with your SNMP agents. 

- fyi, large packet loss can be a sign of network congestion, misconfigured devices, or issues with HBAs and their communication with the SAN. Use the diagnostic tools and analyze traffic between your servers, HBAs, and the network. Identify where the error occurs and whether it's related to broadcast traffic or SNMP monitoring.

-Check the Maximum Transmission Unit (MTU) settings on your HBA and network interfaces to confirm they are correctly configured.

- Properly Configure CA for SNMP and Power Advisor

- Configure Hewlett Packard Power Advisor to use TLS encryption for communication with HBAs and SNMP agents, ensuring that data integrity and security are maintained

- Run comprehensive tests to ensure that Power Advisor correctly monitors the power usage of HBAs without errors. Validate that SNMP traffic is secure, properly isolated, and that no large packet loss occurs. Use monitoring logs to review any abnormal behaviors in the communication between the Power Advisor and your HBAs.

- Review SNMP logs to catch any anomalies or unauthorized access attempts. Misconfigured SNMP agents can result in errors or vulnerabilities that expose your network to broadcast attacks.

I hope these gives some insights. If not, please call the support for further assistance.

Hello 

The procedure tecnichal indicate is correct to design of network. But in the autorithie in ambient not is possible change all propiety.

* The upgrade agent SNMP v3 in power advisory is correct. 

* The depot in HP-UX indicate new feature.

*  In support the SLA is incorrect to ambient of productiont

* The resources as limited and generate overhead to memory for loop incorrect. See example the link domain to referent HPE support "skiforum.it".

* The first problem is in ambient of productiont , the image not is possible change.

* In the forum to support of Hewllet Packard exists incorrect indicationts. 

* The HBA assign hardware addresss and in IRQ interruptiont generate lost LUN ID assign 

* The Vlan betheen Storage and HBA for hash incorrect provocate increase traffic. 

* The  VPN generate secure process to communicationt, but the buffer in network provocate a loop. 

* The LUN assigned to Storage is incorrect again. 

* The homologationt in ambie medical caere , not is possible change all part. The carrier network for loop provocate in string incorrect informationt. 

* If possible RMA to HBA, but not is possible any time generate loop and recurrence in carrier. 

Best Regards

Hellow respond again in your indicationt of security

* Stop of experimentationt and indicationts of security in medical procedure caere. 

* In rebouild of HBA verifie the adulteration logical in circuit of connectiont. 

* See the link of Argentina Cordoba, and experimentationt medical "RECONSTRUYE TU IMPRESORA Hewlett Packard HP TopCat Calculadora (HP91, 92, 95C o 97)-  https://www.ebay.com/itm/224430152817"

" Indicationt in Head HBA "SWiss made" the protocol of ambient is incorrect and deprecate economic and ethical procedure in Homologationt

* Exists incorrect procedure in certificate. 

[FabianCohen1]

Again  respond  in Certificationt of year 2013 Hewllet Packard Enterprise HP-UX 11i v3

* The bussiness world is United State, Latin Americ, Europe Union. 

* The protocol in medical caere and relation ships, not permit adulteration of picture to medical caere. 

* The homologationt repond and Ethical conduct , Ontologic responce in question of Integrity and not permit experimentationt. 

* In your indicationt of security in ambient medical exists develop of network, logic develop in integrate incorrect to specificationt of sound 

.* The time and the cost in system is necesarry, and the publicationt provocate incorrect conduct, the develop is in mentally unbalanced. 

* The procedure in publicationt is a risk for all members 

* The check procedure in protocol of communicationt in UDP is incorrect and provocate incorrect resolutiont in assign LUN to HBA. 

[FabianCohen1]

Hello , Respond please this site and publicationt not is a correct develop, not is correct procedure in medical caere. 

The adulterationt of picture in medical caere is incorrect. 

The integrity in people is affectated for game and incorrect term of Internet in celphone. 

Whats is the correct process of homologationt services. 

The adulterationt in celphone, the adulterationt in procedure of law and the adulterationt in perceptiont encrease the cost for all people, in special to experiment.  The incorrect manipulationt is to year 2013 and in year 2024 again manipulate incorrect procedure 

Again Best Regards

Hello how are you?

In services delivery in Cordoba Argentina, the mail post UPS requiered the firm of send products. Not is one possibility send product and adulterated devices of Hewllet Packard. But this point not is important, the important is de picture and data resguard in system, 

The develop in Depot SNMP v3 of comunicatiint to Cisco System is incorrect.
