X4-2 can be ordred with different type of RAID-card.
From You post is not clear what ESXi version you use.
One of popular RAID card for this server is LSI-based RAID card.
In this case this link can be usefull:
Thank you for your response.
ILOM stated SCSI controller is "Sun Storage 6Gb SAS PCIe HBA, Internal".
And Esxi version, "ESXi-6.7.0-20190402001-standard".
I am reading your recommended URL and try to get hint from the clue.
Hello Cho bon,
Can you please be more specific about the RAID card controller information in ILOM?
What does the following command show?
-> show /System/PCI_Devices/Add-on/Device_4
There are 2 types of LSI (Broadcom) 8 port 6Gb HBA controller available for Sun Server X4-2, one is called Erie (SGX-SAS6-INT-Z) and one is called Niwot (SGX-SAS6-R-INT-Z)
Erie is using sas2ircu utility to manage the disks (https://www.broadcom.com/support/oem/oracle/6gb/sg_x_sas6-int-z ) and Niwot is using MegaCLI utility (https://www.broadcom.com/support/oem/oracle/6Gb/sg_x_sas6-r-int-z )
Alternatively you can use MegaRAID Storage Manager (MSM) which is a nice GUI tool. More information can be found here:
I hope this helps.
