Environment

VMware vSphere ESXi

Cause

The SD Controller does not support the SCSI Command 0x1a (MODE SENSE(6)).

Resolution

This issue is resolved in VMware vSphere ESXi 7.0 U1c and vSphere ESXi 6.7 Patch ESXi670-202011002.

To download ESXi 6.7 Patch ESXi670-202011002  OR to download ESXi 7.0 U1c go to Broadcom Support portal.

Refer Broadcom KB for complete brevity on steps required to dowload the respective Patch / ISO image for ESXi - VMware vSphere downloads, VMware Converter, OEM custom images, patches and addons in the Broadcom Support Portal

 

Workaround:
To workaround this issue increase log rotation and log size as shown in Broadcom documentation - Configure Syslog on ESXi Hosts

Additional Information

T10 states (https://www.t10.org/ftp/t10/document.08/08-309r1.pdf):


The MODE SENSE(6) command (see table 96) provides a means for a device server to report parameters to an application client. [...] If an application client issues a MODE SENSE command with a page code or subpage code value not implemented by the logical unit, the command shall be terminated with CHECK CONDITION status, with the sense key set to ILLEGAL REQUEST, and the additional sense code set to INVALID FIELD IN CDB.

This is not returned in this scenario.

Impact/Risks:
Does not affect the functionality.
