[Kernel-packages] [Bug 1751813] Re: Ubuntu 18.04 installer does not detect any IPR based HDD/RAID array [S822L] [ipr]

The scan is forced to be done synchronously, however the ipr driver is available and is loaded much earlier in the install process, thus it should not significantly affect the overall install time. One may be able to notice the difference a bit more with a fully- automated preseed install. **

In light of comment #51 above, I shall pursue uploading a udev-udeb with modprobe.d config snippet that forces scsi_mod.scan=sync. ** Also affects: systemd (Ubuntu) Importance: Undecided Status: New ** Changed in: systemd (Ubuntu) Status: New => In Progress ** Changed in:

[Kernel-packages] [Bug 1751813] Re: Ubuntu 18.04 installer does not detect any IPR based HDD/RAID array [S822L] [ipr]

So my current feelings about this are as follows: udev-udeb should ship /lib/modprobe.d/ directory It should contain systemd.conf, just like the deb udev package, which sets bonding max_bonds=0 and dummy numdummies=0. It should also contain scsi-scan-sync.conf that that sets `options scsi_mod

Can somebody please test that booting d-i with `scsi_mod.scan=sync` on the kernel command line, on the previously affected system, makes IPR discovery work as expected, by the time one reaches the partitioning menu without any mitigations required from the user? -- You received this bug

[Kernel-packages] [Bug 1751813] Re: Ubuntu 18.04 installer does not detect any IPR based HDD/RAID array [S822L] [ipr]

Two things. SCSI_SCAN_ASYNC=y is set from xenial to bionic. If we believe this is what is causing the race here, we can try booting d-i with a kernel parameter 'scsi_mod.scan=sync' specified. (or i can rebuild d-i with such kernel cmdline built-in if required). And check if that helps to resolve

[Kernel-packages] [Bug 1751813] Re: Ubuntu 18.04 installer does not detect any IPR based HDD/RAID array [S822L] [ipr]

It sounds like the root cause of this bug, then, is that the ipr driver is taking longer than normal / longer than reasonable to initialize+scan. If this is a regression vs. previous Ubuntu releases (as opposed to, say, an instance of failing hardware on a particular test machine), then we need
