Sun Fire[TM] V60x/V65x Server: Boot Kernel Panic Attaching External SCSI Devices (Doc ID 1012170.1)

Last updated on OCTOBER 30, 2020

Applies to:

Sun Fire V60x Server - Version All Versions to All Versions [Release All Releases]
Sun Fire V65x Server - Version All Versions to All Versions [Release All Releases]
All Platforms

Symptoms

When connecting an external SCSI device, the drive letters change in a Linux system. This confuses the kernel during boot and leads to a "Kernel panic".
Disabling "HostRAID Support" and "SCSI Controller Int 13 Support" (mentioned in the release notes) does not change the situation. The last three lines of the boot log show the following or very similar error messages:

VFS: Cannot open root device "sda5" or 08:05
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 08:05
