Fix: My annoying Boot from San Issue with BL45p Blade (Update)

. Tuesday, September 30, 2008

My company recently bought 3 "new" HP blades - a nice addition for existing HP p-Class chassis. Why new in quotes - since technically the models are no longer current in HP model line, and they had to be bought from external vendor we don't usually use - but all purposes they are new for us.

BL20p G3 were pretty easy to setup as boot from out NetApp 3020 SAN, but the bl45p G1 was stubborn as an donkey.

There problem was during POST the Qlogic HBA didn't recognized the LUN and therefore , skipped on loading the HBA's bios = No boot.
However in Qlogic config utility (the CTRL-Q) I had all settings done correctly and the fiber scan shows the LUN correctly.

It took me 5 days of troubleshooting, trying different configs and getting ideas and opinions from colleagues and experts friends.

Nothing Helped! ;-(

Until a colleague given me an idea - to connect the same fiber/lun to different blade and only one as free was bl25 - despite totally different hardware (AMD vs Intel - BSOD pretty much guaranteed) it was still important test to see if its the fabric/lun/config issue. BL25 booted from lun perfectly every time (as well as BSOD every time as well)

A total surprise to me was a solution which I got from 2nd level supporter at HP after convincing them I need to escalate the issue and It's not 3rd party problem -


It looks like part of Cmos settings got corrupted, but there was no indication in bios for that....

Update: Looks like after all it was problem with bad fiber…. :(

Baltimore becomes the first Xohm WiMAX (4G) City

. Monday, September 29, 2008

Sprint's Xohm WiMAX service begins this morning in Baltimore, Maryland. Customers will be able to pay for daily or monthly access to the 4G wireless service without long-term contracts or usage caps.

The expected average downlink speed for the service will be 2-4 Mbps and will cost either $10 per 24-hour block of time or $35 per month for home access and $45 per month for "on-the-go." Sprint also offers multi-device packages in anticipation of future hardware availability.

The current Xohm hardware is currently limited to the desktop modem by Zyxel for $79.99, and the expresscard modem by Samsung for $59.99. A USB XOHM modem made by ZTE is listed but not yet available.

By not requiring a contract, Sprint is encouraging non-customers to test the service out to see for themselves. For a service that has thus far been difficult to establish, a strong public reaction is needed if it is to progress.


I have my own reservation about this - One one hand $15 Reduced prices for 6 months and no need for contract might help save up to $90 to price conscious Wireless internet users, but in long run prices being about same as 3G data service and about same speeds, Sprint will have a hard time for next year or so, until Intel will really start the push to include WiMax adapter in every "Centrino 3" laptop , just like they did with first generation with Wi-Fi - The "No WiFi - No Centrino Label" Policy, and Inside sources tell it'll comparable or bigger push than original platform.

How to Eject BOTH Magazines from Quantum Superloader 3 Tape Autoloader/Library

. Thursday, September 25, 2008

This time around drive inside out above mention tape library broke down and after extensive troubleshooting with, somehow I felt very reluctant, Quantum support people (with heavy south-east Asia accents) they finally agreed to send an onsite engineer to fix it. How silly is was from me to assume this qualified service engineer is going to fix anything or perform onsite drive replacement. As it turns out that the tape drive in this model of autoloader - 3, CAN NOT be field replaced and a Quantum solution is to ship WHOLE NEW LIBRARY. Bear with me - this unit is 2U Full Length sized, holding up to 16 LTO (1/2" sized) tapes.

Now to the juicy part:
The library in its normal operation allows only one of two it's tape magazines to be ejected at the same time, however, the new unit came without magazines so we need to change between them. Reading documentation revealed nothing but a short mention of the mysterious "manual" removal procedure, but no mention of exactly that needs to be done. Short phone to support lifted the mystery: A very special tool required for a job - stainless steel ruler! Or in lack of one I successfully used a diner/bread knife. The trick is to insert into the lower part of the slot between magazine and mailslot (Look on the image below) for about 3" deep until you hear a quiet click and you'd be able to release 2nd magazine.
I strongly suggest you fully power down the autoloader before performing this operation.
