    Solaris boot problem after Patch cluster install

    807559
      just wondering if anyone can assist. i have just installed solaris 10 x86 recommended patches on a 16 disks server. where first 2 disks are mirrored called rpool, and remaining 14 disks are raid z called spool. upon installing the patches successfully and rebooting server, i am coming up with the following error:
      ---
      NOTICE: Can not read the pool label from '/pci@0,0/pci8086,25f8@4/pci111d,801c@0/pci111d,801c@4/pci108e,286@0/disk@0,0:a /pci@0,0/pci8086,25f8@4/pci111d,801c@0/pci111d,801c@4/pci108e,286@0/disk@1,0:a'

      skipping system dump - no dump device configured
      rebooting...

      It looks like the solaris 10 os cannot find zfs filesystem and keeps on rebooting in normal solaris os mode, but when I go to safe mode and type: zfs list, I can see zfs rpool (mirrored) file system and cannot see the zfs spool (raid z) file system, any ideas on how i can fix the boot problem and get zfs spool back in the safest way possible?...

          Same problem here with actual recomended patch set.

          NOTICE: Can not read the pool label from '/pci@0,0/pci10de,375@f/pci1000,3150@0/sd@0,0:a /pci@0,0/pci10de,375@f/pci1000,3150@0/sd@1,0:a'

          What the hell happened to the bootsektor or the pool or what ever?

            This problem is likely due to patch 142901-1x that is contained into the recommended x86 Patch cluster and it modifies SUNWzfs* and SUNWgrb* packages. This issue is currently under investigation.
            As temporary work-around do not install Kernel patch 142901-1x.

              Hi!

              I saw this "cannot mount root" stuff too yesterday on X4150. I used PCA to install patches using patchdiag.xref from 9 july 2010. Rolling back this kernel patch removed the issue (and presented some others which I managed to resolve).

              Update:
              After upgrading U7 -> U8 and patching with LU, the problem went away.
