Hello everyone,
I have an interesting problem that I am absolutely stuck on and
would appreciate any help. The setup is a Dell 1950 III with a Dell
SAS 6/iR internal card and an Dell SAS 5/E controller connecting to
a Dell MD3000. What I am looking to do is have the MD3000 serve up
each of its drives and have ZFS do raidz across them all.
The issue I am having is every other virtual disk (the MD3000 does
not have a JBOD option so you have to create a bunch of RAID 0
single disk volumes that the MD3000 calls a virtual disk) that the
MD3000 creates does not get recognized by OpenSolaris. OSOL sees
the disk but cannot read the partition table on them. Why this is so
weird is that it is only on half of them, not all of them. Here is
the output from format:
0. c7t0d0 <DEFAULT cyl 8750 alt 2 hd 255 sec 63>
/p...@0,0/pci8086,2...@3/pci1028,1...@0/s...@0,0
1. c11t6d0 <drive type unknown>
/p...@0,0/pci8086,2...@6/pci8086,3...@0/pci1028,1...@8/s...@6,0

/p...@0,0/pci8086,2...@6/pci8086,3...@0/pci1028,1...@8/s...@6,3
Running fdisk -v -W - /dev/rdsk/c11t6d2p0 produces
Error in ioctl DKIOCGMBOOT: I/O error
fdisk: Error reading partition table from /dev/rdsk/c11t6d2p0.
It is not the physical drive because I have tried switching them
around.
I have updated the MD3000 firmware to the latest, updated OSOL from
svn_111b to dev svn_134. Hell I even updated the drive firmware
just for fun, but the behavior is always the same.
Any help would be great!
MD3000 is an active/passive multiport array. Enable mpxio and disable
cache flush on it.
Yes OS does work with it.
For best performance alternate the controller that the lun handles.
Lun 0 controller 0, lun 1 controller 1, etc.
