Troubleshoot PSOD on ESXi 5.5 due to HPSA driver 5.5.0.58-1

We received lot of Purple Screen of death(PSOD) on ESXi host 5.5. When analyzed the logs and googled related to the error, It comes to know that it is a known issue with hpsa (HP ProLiant Smart Array Controller ) driver affecting ESXi 5.5. It is causing memory leak associated with device rescans resulting in out of memory conditions and a potential PSOD. HP has released the latest version of HPSA. HP has released the latest version of HPSA driver (5.5.0.60-1) for vSphere 5.5.
ESXi5.5 - Purple Screen of Death (PSOD)
Below issues were addressed as part of this latest HPSA driver version
  • Fixed a memory leak associated with device rescans resulting in out of memory conditions and a potential PSOD.
  • Fixed a null pointer dereference in error handling code that can cause a PSOD in rare cases when device inquiries fail.
  • Restore LUN numbering policy to start with 1 instead of 0, avoiding potential issues with Raw Device Maps.
  • Enable 64bit DMA mapping instead of default 32bit mapping.
  • Improve null pointer checks in device rescanning code, avoiding a potential PSOD.
  • Restore maximum outstanding command count, removing artificial limitation that could impact performance.
  • Restore support for legacy HP Smart Array P700m controller.
To identify the current version of HPSA driver installed with your ESXi 5.5 host, execute the below command:
~ # vmkload_mod -s hpsa | grep Version
Version: Version 5.5.0.58-1OEM, Build: 1331820, Interface: 9.2 Built on: Dec16 2013
Driver Version: HP HPSA Driver (v 5.5.0.58-1OEM)” meant the affected software driver was used.

How to Install the latest HPSA driver for ESXi 5.5:

Download the HPSA driver vib file (scsi-hpsa-5.5.0.60-1OEM.550.0.0.1331820.x86_64.vib) for vSphere 5.5 and upload it in your ESXi host datastore
1.Place your ESXi host into Maintenance Host
2.Install the hpsa driver VIB using the below following command:
esxcli software vib install -v /tmp/scsi-hpsa-5.5.0.60-1OEM.550.0.0.1331820.x86_64.vib
ESXi-HPSA driver installation-VMware Arena
3.Reboot the ESXi host for the changes to take effect
4.Verify the HPSA driver version after the installation using the below command:
~ # vmkload_mod -s hpsa | grep Version
Version: Version 5.5.0.60-1OEM, Build: 1331820, Interface: 9.2 Built on: May 15 2014
5.Exit your ESXi host from the Maintenance mode
Thats it!!. No more PSOD on your ESXi host. I hope this is informative for you. Thanks for Reading!!! Be Social and share it in social media, if you feel worth sharing it.

It should be emphasized that VCFA is a new solution and not just rebranding of an old one. However it reuses a lot of components from its predecessors. The provider part of VCFA called Tenenat Manager is based on VCD code and the UI and APIs will be familiar to VCD admins, while the tenant part inherist a lot from Aria Automation and especially for VCD end-users will look brand new. Deployment and Architecture VCFA is generaly deployed from VCF Operations Fleet Management (former Aria Suite LCM embeded in VCF Ops. Fleet Management...

  Issue with Aria Automation Custom form Multi Value Picker and Data Grid https://knowledge.broadcom.com/external/article?articleNumber=345960 Products VMware Aria Suite Issue/Introduction Symptoms: Getting  error " Expected Type String but was Object ", w hen trying to use Complex Types in MultiValue Picker on the Aria for Automation Custom Form. Environment VMware vRealize Automation 8.x Cause This issue has been identified where the problem appears when a single column Multi Value Picker or Data Grid is used. Resolution This is a known issue. There is a workaround.  Workaround: As a workaround, try adding one empty column in the Multivalue picker without filling the options. So we can add one more column without filling the value which will be hidden(there is a button in the designer page that will hide the column). This way the end user will receive the same view.
