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 ![]()
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)

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
