ESXi 5.1 U3: Failed to add path vmhba1:C0:T0:L0 : Failure (for Tandberg RDX backup drive) - HELP

Hello all!

I have installed VMware ESXi 5.1 Update 3 on a new HP Server machine and I experience some strange error.

Please help me to solve the issue, any hints appreciated Smiley Happy

Current setup:

- ML310e Gen8 server

- LSI SAS PCIe Controller (non RAID)

- TANDBERG RDX backup drive attached to LSI SAS controller

- LSI driver updated to latest version 20

- Firmware of server, controller etc.. at latest revision

Goal:

I would like to map the Tandberg RDX drive to the virtual machine to perform backups.

Problem:

The backup drive is not shown on the storage controller. On the ESXi console I get following error in "dmesg":

2015-01-25T16:23:08.794Z cpu3:4184)ScsiScan: 888: Path 'vmhba1:C0:T0:L0': Vendor: 'TANDBERG'  Model: 'RDX             '  Rev: '0044'

2015-01-25T16:23:08.794Z cpu3:4184)ScsiScan: 891: Path 'vmhba1:C0:T0:L0': Type: 0x0, ANSI rev: 3, TPGS: 0 (none)

2015-01-25T16:23:08.796Z cpu3:4184)WARNING: ScsiScan: 1276: Failed to add path vmhba1:C0:T0:L0 : Failure

Unfortunately I get no further errors or a description what could be wrong.

I tried to set SATP rules:

esxcli storage nmp satp rule add --satp="VMW_SATP_LOCAL" --driver="mpt2sas" --claim-option=tpgs_on

and

esxcli storage nmp satp rule add --satp="VMW_SATP_LOCAL" --vendor="TANDBERG" --model="^RDX*" --psp=VMW_PSP_FIXED --claim-option=tpgs_on

reboot the server but no luck.

Same issue.

Another possibility was to map the SAS PCIe controller directly to the virtual machine.

I enabled PCI passthough (Intel VTd etc.. all enabled in BIOS!) and added the PCI device to the virtual machine but when powering on "passthough is not enabled on device". I stopped then searching further to solve this issue and returned to the native SAS/SATA mapping of the device into the virtual machine.

The CDROM drive, which is connected to the internal SATA controller, is showing in the list when I try to add a new SCSI device to the virtual machine.

Another observation:

The directory /vmfs/devices/genscsi/ does have only the onboard SATA controller, there is no vmhba1 shown but available as adapter:

~ # esxcli storage core adapter list

HBA Name  Driver   Link State  UID                   Description                                               

--------  -------  ----------  --------------------  -----------------------------------------------------------

vmhba1    mpt2sas  link-n/a    sas.500605b003f1ec70  (0:7:0.0) Avago (LSI) Logic / Symbios Logic Avago (LSI)2008

What can I do to further diagnose the issue and solve it?

Which diagnose output is required to get a better clue about whats wrong?

Thanks for your help!


Best regards,

Bernhard

just an opnion

backup devices pass through is a nightmare for me

i always use an other server to make backups

so my recommendation is to remove the RDS backup device and put it in another server

kind regards Vervoort Jurgen VCP6-DCV, VCP-cloud http://www.vdssystems.be
