OpenSolaris is a best platform for out-of-the-box NAS

2009-10-07T15:20:00.005+02:00

The benchmark that was done by Flexense shows that
OpenSolaris beats all other OS'es as a NAS platform.
Good news.
Not a surprise for me, though.

FCP_VOLUME_ADDRESSING is supported in snv_113 ?

2009-05-07T10:18:00.005+03:00

Finally I have time to install snv_113 to test the fix of the bug 6487899 that I've reported 2.5 years ago. Here's the timetable :

SC 3.2 / Solaris 10 u6 / e1000g

2009-02-04T14:26:00.003+02:00

Just hit a bug "GLD interfaces unexpectedly send VLAN tagged packets" when luupgraded the SC 3.2 to s10 u6. After the upgrade cluster private interconnects of three T2000 nodes could not come up. Yet another sleepless night at customer's site...

Boot-from-SAN-root-zpool behavior

2009-01-14T16:30:00.008+02:00

Root-zpool sitting on SAN disk is configured by default in S10 10/08 with failmode=continue attribute
It means that it...
"Returns EIO to any new write I/O requests
but allows reads to any of the remaining
healthy devices. Any write requests that
have yet to be committed to disk would be
blocked."
The default behavior is: the LUN is offlined 20 sec[1] after the disk disappears from the fabric. The following error message appears on the console:
scsi: WARNING: /pci@780/SUNW,qlc@0,1/fp@0,0/ssd@w5001738000160141,7 (ssd0):
Command failed to complete...Device is gone
when MPxIO is disabled
or
scsi: WARNING: /scsi_vhci/ssd@g0017380000160008 (ssd1):
drive offline
when MPxIO is enabled.

The system is hung and must be restarted.

[1] "Within the LV stack (Leadville), there is a 20-second delay to avoid any
unintentional removal of the cable. This ensures that the loss of sync
is due to a failure and not due to removing the wrong cable and then
realizing the mistake. The 20 seconds is used to correct the mistake.
If they do not put the cable back within 20 seconds, error recovery
will start."

luupgrade problems with second SAS drive on T1000

2008-05-20T12:15:00.005+03:00

luupgrade could not configure the second SAS disk of my T1000 as bootable.
It is invisible for the show-disks OBP command...looks like a bug:

{1} ok show-disks
a) /pci@7c0/pci@0/pci@8/scsi@2/disk
q) NO SELECTION
Enter Selection, q to quit: q

probe-scsi shows the disk:

{1} ok probe-scsi
This command may hang the system if a Stop-A or halt command
has been executed.  Please type reset-all to reset the system
before executing this command.

As a workaround, I've shut down the server after unsuccessfull luupgrade and ran this cmd:

It booted fine, but the lustatus is unaware of any boot environments that were created before this boot.

Nextra vs Symmetrix

2008-03-09T11:01:00.001+02:00

Which storage arrays present themselves as "Array Controller" ?

2008-03-03T12:40:00.012+02:00

HP StorageWorks EVA3000/5000 4.004
HP StorageWorks EVA4000/6000/8000
HP StorageWorks XP128/1024
HP StorageWorks XP10000/12000
Compaq Storageworks RA4100

If you know any other storage array presented as "Array controller" (device type 0xC), please let me know.
(Yes, I know about Nextra.)

Update: Symmetrix presents its LUN 0 as "Array Controller" device type when the V-bit (Volume Set Addressing) is turned on.

Martin Paul's PCA tool saved me a lot of time, headache and nerves. That's why I used an opportunity to add my feedback about it in Gerry Haskin's "Patch Corner" blog.

Everybody is welcome do add her 2 cents to the discussion.

SunCluster 3.2 in action

2007-12-26T18:30:00.002+02:00

Three T2000 servers connected to six racks of decent XIV storage (38TB each) plus FC and GBE switches, that's the HA NFS SunCluster 3.2 in action.

SC3.2 on T2000? Disable the clhbsndr!!!

2007-11-30T12:12:00.000+02:00

Useful tip for all those who are running network-intensive services on SunCluster3.2 on T2000/T1000:
Comment the following line in /etc/iu.ap:

e1000g  -1      0       clhbsndr

It will improve the performance.

Why reboot_on_path_failure is useless when you're using ZFS with SunCluster 3.2

2007-10-08T19:25:00.000+02:00

Why enabling the reboot_on_path_failure won't help on SC3.2 with ZFS ?
Because the cluster node will panic with

"ZFS: I/O failure"

before the scdpmd will figure out the problem.
What it means is: the ZFS is doing the scdpmd work much faster. It causes the host crash after first IO to the unaccessible (disconnected) storage. The scdpmd is checking storage every 10 minutes (!).
To make it works with ZFS, the bug 6322646 must be fixed.

Here's more detailed explanation.

Enabling jumbo frames for Sun x8 Quad NIC

2007-09-24T01:15:00.000+02:00

You need to enable jumbo frames for Sun x8 Express Quad Gigabit Ethernet Adapter?
For Solaris 10 u4 (aka 8/07) these settings won't help :

ndd -set /dev/nxge0 accept_jumbo 1
accept_jumbo = 1; in /kernel/drv/nxge.conf

And this one will do the job :

set nxge:nxge_jumbo_enable=1 in /etc/system
and add "mtu 8000" to /etc/hostname.nxge0

Thanks to Vitaly for pointing me to this workaround.

OS Live Upgrade of SunCluster 3.2

2007-09-07T00:15:00.000+03:00

We'll start with the good news :

Solaris 10 u4 is available

SunCluster 3.2 supports Live Upgrade

What does it mean? Now it's possible to upgrade the OS version of the cluster nodes without interruption of running services. The prerequisites are: the cluster version is 3.2, it's not a single-node cluster and the nodes are running Solaris 10.

Let's do it step-by-step:

Create a new BE (Boot Environment)

      lucreate -c s10u3 -m /:/dev/dsk/c0t0d0s3:ufs -n s10u4

Upgrade the new BE

      luupgrade -u -n s10u4 -s /net/myserver/s10u4

Activate the upgraded BE

      eeprom diag-switch?=false (for SPARC only)

      luactivate s10u4

Switchover the Resource Groups and reboot the cluster node

      clrg switch -n node2 rg1

...

      clrg switch -n node2 rgN

      init 6

Proceed steps 1-3 on the second, third, etc. nodes

Congratilations! We're done:

# cat /etc/release

luactivate and EEPROM
