Oracle Sun SAS 6GB/s PCI-E驱动适配问题求助

Hey there, let's work through this frustrating Sun SAS card issue together—you're not stuck with a paperweight yet!

First, let's get clear on the core of the problem: your card uses the PM8001c chip from Broadcom (formerly PMC-Sierra), so the LSI/Adaptec drivers you tried were never going to work—they're for entirely different chip families. Here's what you can try step by step:

• Target the right driver source: Focus on Broadcom's legacy PM80xx series drivers for Windows 10. Look for the "PMC-Sierra PM8000 Series SAS/SATA Controller Drivers" package, specifically the x64 version (since you're on Win10 Pro, it's almost certainly 64-bit). Skip the auto-installer if it crashes or fails—go for manual driver installation instead:

  1. Open Device Manager, find the unknown SAS card (it'll probably be under "Other devices").
  2. Right-click it → "Update driver" → "Browse my computer for drivers".
  3. Point to the folder where you extracted the Broadcom driver files, and let Windows scan for the correct .inf file. This bypasses any OEM-specific checks in the installer that might block the card.

• Fix hardware ID mismatches: If Windows still doesn't pick up the driver, check your card's 硬件ID (right-click the device → Properties → Details → Hardware IDs). Copy the top entry (looks like PCI\VEN_1000&DEV_XXXX&SUBSYS_XXXXXX), then open the .inf file from the Broadcom driver package in Notepad. Search for existing entries for the PM8001c, and add your exact hardware ID to that list (make sure to save a backup of the original .inf first!). Then try the manual install again—this often works for OEM-customized hardware like Sun's cards.

• Try Server OS drivers as a fallback: Windows 10 shares a lot of kernel code with Windows Server 2016/2019. Grab the Broadcom PM80xx driver for Server 2016, extract it, and repeat the manual installation steps. Most server hardware drivers are backward-compatible with desktop Win10, and this has worked for many people with Sun/Oracle server cards.

• Check community resources: Since Oracle won't help individual users, head to server hardware forums or storage-focused communities. Lots of hobbyists and IT folks have shared extracted drivers or workarounds for this exact Sun SAS card—someone might have already modified the driver to work seamlessly on Win10 for their LTO tape setup.

Don't give up yet—this card's definitely salvageable for your backup library!
