We have an A1000 that we're trying to use with Solaris 10
and RM6. The can be configured and monitored, and it
appears to work correctly, except for problems with the
RDAC drivers.
Questions are:
- Is there a version of RM6 that works under Solaris
10?
- Are there any other problems or incompatibilities
(other
than with the RDAC multi-pathing) that I need to be aware
of?
- Is this a "safe" configuration to run?
Details:
- SunFire 480R with dual-differential HBA
- Netra A1000 (single controller)
- Solaris 10 (3/05)
- RM6.1.1 Update 2
A) The array can be configured and managed just fine using
the command-line tools in /etc/raid/bin. Specifically, LUN
and hot spare creation appears to work, healthck and
various "drivutil" status options work, and I "failed" a
drive and watched the array rebuild onto the hot-spare.
B) The LUNs created can be accessed, partitioned, newfs'ed
and mounted using the usual unix tools. HOWEVER, the RM6
software and unix don't agree on the SCSI controller
numbers. RM6 (eg from "lad") sees the array at c2t5d0s0.
But unix sees the volumes on c4t5dXsY. The underlying
physical devices are listed as:
c2t5d0s0 -> ../../devices/pseudo/rdnexus@2/rdriver@5,0:a
c4t5d0s0 -> ../../devices/pci@8,700000/scsi@3/sd@5,0:a
C) The kernel complains to the console on startup :
... NOTICE: rdnexus: 64-bit driver module not found
... WARNING: forceload of drv/rdnexus failed
... NOTICE: rdriver: 64-bit driver module not found
... WARNING: forceload of drv/rdriver failed
And later in the startup "rdaemon" complains:
... Could not open RDACnode(/dev/osa/dev/rdsk/rdac),
errno=6(No such device or address)
Presumably rdnexus and/or rdriver aren't loading because
they are 32bit only, and "rdaemon" can't start because it
needs them. However the other daemons "arraymon" and
"parityck" run fine.
D) We're not running multiple controllers, so we can live
without multi-pathing. Are there any other side effects of
these drivers not loading? And are there other problems
with this configuration?
Please email me an I'll summarize to the list. Thanks in
advance...
