OEL stopped seeing Sun Storage 7420

My organization had relocated a small handful of servers between racks. While we plugged everything back exactly the way it was, our cloud control server was unable to see the devices presented through our Sun Storage 7420 over FC.
I've assured the Fibre ports were lit up and plugged back in the same exact spot they were before.
I can see all 4 FC ports on the OEL system:
[sanitized]# lspci | grep -i fibr
0b:00.0 Fibre Channel: QLogic Corp. ISP2532-based 8Gb Fibre Channel to PCI Express HBA (rev 02)

I've made sure the DM modules were loaded at boot:

Checked multipathd:
# service multipathd status
multipathd (pid 4306) is running...
Made sure we had a device section under multipath.conf:
device {

prio_callout "/sbin/mpath_prio_alua /dev/%n"
hardware_handler "0"
path_grouping_policy group_by_prio
failback immediate
no_path_retry queue
rr_min_io 100

I've rescanned the 4 host ports from the FC:
# echo "1" > /sys/class/fc_host/host3/issue_lip
# echo "1" > /sys/class/fc_host/host4/issue_lip
# echo "1" > /sys/class/fc_host/host5/issue_lip
# echo "1" > /sys/class/fc_host/host6/issue_lip
Checked to see if /proc/scsi/scsi has updated:
Attached devices:

I've also reviewed the output from fdisk -l:
# fdisk -l | grep Disk
Disk /dev/dm-0 doesn't contain a valid partition table

I am really unsure where else to look at getting this functional again...

Recreate pool problem on a 7110 Sun Storage

Hi,
we have a Sun 7110 that runs mostly well, except when the iscsi volume fills up, the volume stop, and we have to drop it and recreate it. 3 weeks ago, to counter that, I switched on dedup and compression. No idea if it is a good or bad idea, but because we got lots of i/o hanging on the volume :
- we tried to drop again the volume via the web interface.
- after destroying it, impossible to recreate it, so we switch to the shell to see what's going on. In fact all space was filled up into the "zombie" share (pool-0/???/zombie). No idea what it is, because we never got snapshots. And the cpu was still in the roof like it was still compressing, deduplicating or what...
- we decided to connect to destroy the whole pool (with difficulty), and the CPU stop working as crazy
Now impossible to recreate it via the web interface.
- i can create the pool with zpool and create volume with zfs but they don't show up in the interface
- if we destroy again and try to create it in the web interface, we have of course no pool in the "Available pool", so I try to create it BUT i can't:
Model     Sun Storage 7110
Data Devices     -
Log Devices     -
Cache Devices     -
as is there weren't any disks!
I checked : the disks are ok from the OS point of view (/var/ak/logs/debug.sys doesn't complain for example, except for a spare disk that I labeled back)
Any idea how to "reset" the storage pool?
Do I must go through the "factory reset" (I'm not even sure it can help).
Or should I forgot Sun/oracle appliance kit, and install freenas instead? :-)
Any help will be appreciate (or similar concerns :-) )
Nicolas Zin

I answer to myself:
factory reset solved the problem.
Dawn box!

New major release of Sun Storage 7000 software is available

I noticed a new major release of the Sun Storage 7000 software is available at the website below.
http://wikis.sun.com/display/FishWorks/Sun+Storage+7000+Series+Software+Updates.

The format change is for BDB Java Edition 5.0 only, and does not apply to other BDB products. It's forward compatible, which means that a BDB JE application using JE 5.0 can use environments written with older versions of JE. However, it's not backwards compatible; once your environment has been opened by JE 5.0, it's been converted to the new format, and can no longer be readable by older versions of JE.
Just for the benefit of others who may not have read the changelog, here's the full text:
JE 5.0.34 has moved to on-disk file format 8.
The change is forward compatible in that JE files created with release 4.1 and earlier can be read when opened with JE 5.0.34. The change is not backward compatible in that files created with JE 5.0 cannot be read by earlier releases. Note that if an existing environment is opened read/write, a new log file is written by JE 5.0 and the environment can no longer be read by earlier releases.
There are two important notes about the file format change.
The file format change enabled significant improvements in the operation performance, memory and disk footprint, and concurrency of databases with duplicate keys. Environments which contain databases with duplicate keys must run an upgrade utility before opening an environment with this release. See the Performance section for more information.
An application which uses JE replication may not upgrade directly from JE 4.0 to JE 5.0. Instead, the upgrade must be done from JE 4.0 to JE 4.1 and then to JE 5.0. Applications already at JE 4.1 are not affected. Upgrade guidance can be found in the new chapter, "Upgrading a JE Replication Group", in the "Getting Started with BDB JE High Availability" guide.I may not have fully understood your question, so let us know if that doesn't answer it.

Mac os 10.5 accessing sun storage via smb

Dears
I have three mac 10.3.9 machines .those can access a sun storage device normallyin the same local net using smb.I installed another system 10.5 on those machines, but unfortunately trying to connect to the sun storage you can see the connecting bar for a very long time with no response.I installed a new mac Leopard 10.5.2 machine in the same network , and this last computer can connect to the storage server .So I upgraded the three one's to 10.5.2 with no improvemnt , even to 10.5.5.Those three if restarting as 10.3.9 can be connected .all network settings were checked.
appreciating in advance your help.

I apologize for the delay in responding to you. I was on the road all day yesterday.
OK. I switched the printer's Ethernet cable to a Linksys Switch (Model EZX S55W) that's part of this local network. That did not work. I swapped out the cable for one that I know works. Still no change. I switched the printer's Ethernet cable directly to a port on the router. No change. I even swapped cables here, too, but no success.
As I was doing all this, I was wondering: When I select the HP P1606dn printer in the Print and Fax "Add" dialog box, (see the image below) and the Print Using pulldown menu displays "Please select a driver or printer model" and the message "Searching for new drivers" appears under it (with the spinning wheel), why is it that the Ethernet connection to printer is critical to "finding" a new (printer) driver?
Isn't the utility searching through my system and libraries looking for a printer driver app for the printer that I identified/selected in the dialog box?
After all, if the dialog box lists the printer among those to choose from, hasn't the utility already discovered the printer via the Ethernet connection?

Don't upgrade to Sun Storage 7000 Series 2009.04.10.2.1!

The latest release of AmberRoad firmware (Sun Storage 7000 Series 2009.04.10.2.1) leads to a performance regression. It's recommended not update at this time. See the Fishworks Documentation for more information: http://wikis.sun.com/display/FishWorks/Sun+Storage+7000+Series+Software+Updates

The last two releases (2009.Q2.2.1 and 2009.Q2.2.0) of the AR firmware show poor iSCSI performance.
I therefor recommend to use release 2009.Q2.1.1.

Oracle VM: Sun server x3-2 with Sun Storage 2540 M2

Hello Everyone!
Currently, we are planning to implement a project about Visualization using Oracle VM.
As the Sun Storage 2540 M2 uses FC channel to share its luns from storage, we are not sure on how to discover those share storage luns to be use in Oracle VM manager and Oracle VM Server.
So, could you please help guide us, give us some recommendations, or instruction documents to the issue above?
Thank so much in advance!
Regard,
Dara

Storage Controller set as IDE (the second option to choose is AHCI)
Arch kernel doesn't have support for IDE devices anymore, you should select AHCI. The problem is that if you installed "Windows" with the controller as IDE then it will seace to work when you select AHCI.
For what i've read arround here, there is a workarround for IDE devices, but i don't know if it works anylonger:

Installing Sun Storage C4 - Tape Library on IBM p550Q

All,
Need your advise, what should we prepare to install Sun Storage C4 Tape Library attached to IBM P550Q?
I read the information about supported OS on C4 Tape Library are only Windows, Linux and Solaris. So, how do we reveal with this situation?
regards,
/hendra

I'm looking for the same thing -
Were you able to location any documentation?
I've been trying to get my hands on the documentation
for the C4. Sun's doc site does not have this product
listed at all. The product documentation link
(http://docs.sun.com/app/docs/prod/1878#hic) just
returns " The requested item could not be found."
I've even tried opening up a case with Sun. First,
the support people had no idea what the C4 was. After
3 days and 3 support engineers, I finally found one
who understood what this product was, but I was then
told that getting the documentation would be on a
time and materials basis. I'd rather not have to pay
$400+ for documentation that should be on their
website, just like all their other equipment. I'm
currently using the Quantum PX502 documentation as a
reference, but I'd really like to see Sun specific
documentation.
Any ideas?
Thanks.I'm looking for the same thing -

Mac mini server has suddenly stopped seeing one or the other bluetooth devices! Batteries have been changed and they will connect to an older Mac mini. Server will now only see one or the other but not both.

My Mac mini server has suddenly stopped seeing one or the other bluetooth devices, either the wireless keyboard or the mouse( both apple products) have tried new batteries, at first it was the mouse that stopped responding, but upon rebooting the computer now the keyboard will not respond and the mouse works. Both work fine on an older Mac mini that I hooked back up to check.

There is absolutely no reason why they should not bothe be able to connect to your WiFi network. The easiest place to start would be to reboot your router. Unplug it for about 30 seconds and then plug it back in again. I would also restart both the iPad and the iPhone.

Have you tried resetting the PRAM? shutdown the machine, hit the power button then hold down the option and command keys with your left hand, while holding them down with your right hand use your pinky to hold the 'P' key and index finger to hold down the 'R' key. hold them down until you hear the 'bong' sound twice then release the keys and let the machine bootup.
Also try resetting the SMC. Shut the machine down. Hold down the 'shiftctrloption' keys with your left hand, right hand hold down the power button for 10 seconds then release all. Power up the machine as normal.
Hope this helps. Pls update us and let us know if that helps!

New phone: lost old phone in a fire. How can I access my photos on iCloud from my old phone? In settings I see the storage for BOTH phones. They are separate but same account. Can I access iCloud through PC or is the info now useless since phone is gone?

What a crappy design. This is where Android is so much better. It seems to me like you have no control over your iPhone. It does whatever Apple has designed it to do without asking you first. On Android you can actually go in see all folders, document files, photo files etc and you have so much more control of everything. Apple s..cks!

Recently when I connect Iphone 4s and MacBook Pro my computer stopped see new photos on Dropbox.

Recently when I connect Iphone 4s and MacBook Pro my computer stopped see new photos on Dropbox. I have changed iCloud password on Mac and Iphone, nothing. Deleted some pictures of iPhone, didn't help. Any ideas what I did to mess this up?

I cannot deleted. Computer keep telling that my dropbox is open. Don't see how to shot it off. Do I need to delete all pictures from dropbox first and delete application after. Will I loose all these pictures? Usually, I copy all photos to iphoto app.

Is Sun Storage 7000 Storage replication adapter compatible with 2540 series

We are evaluating VMWare Site Recovery Manager 4.0. Is Sun Storage 7000 Storage replication adapter compatible with 2540 Sun Storage series?

I would say the short answer would be no. The 2540 is a LSI based device, the SRM adapter for that is written by LSI. The 7000
series array is based on OpenSolaris and ZFS, quite a different beast.

IMac (white core duo) has stopped seeing my wi-fi

My computer is in the same place it's been for the last four years. Nothing has changed in our house. My wife's iPad and my iPod Touch still use the wi-fi fine. Two days ago though, my iMac stopped seeing it. It will see it, but it will come and go - and never with full strenght. I get errors saying I'm not connected to the internet, etc. It's crazy and of course I can get nothing done from it (typing this on wife's eMac, wired to the DSL router via ethernet).
What's even stranger is that wi-fi networks I've never seen before show up in my pull down list periodically.
I've restarted the mac, turned off and on the router. I've checked for updates on the mac (none). I'm running 10.5.8 (leopard).
As i've said, nothing has changed about my setup or our house. No new electronics. No new phones. No new anything!
Any help would be appreciated.
thanks

If it turns out it's bad, or if you just want to try something, there are these type things - USB wi-fi adapters. I have never owned nor used one. You permanently lose a USB port, but they might solve your problem at least till you get your next Mac
