FC Disk Firmware

[Kevin Lamb_2]

Hi,

I am trying to find out what the current revision of firmware is for the following disks.

ST336704FC
ST336605FC

At present we have 4x ST336704FC three of which are HP01 and one at HP07

The 6 ST336605FC are all at HP05

We are planning to have the firmware upgraded this weekend but I am a bit dubious of the risks involved, having read through the forums some disk may not return to the up state ans was wondering if this is realy necessary, we have not had any problems with the disks.

The only reason we are going forward with the upgrade is following the advice of one of the Engineers who replaced a failed disk over 2 months ago.

Any assistance would be appreciated.

You are correct that if the firmware has issues with a drive then that drive could be rendered unusable. Because of that, you should take TWO good backups (VERIFIED) of your data!

I would also suggest to PROCEED with the upgrade, that way you are "fully" supported.

Hi Kevin

As with almost any upgrade on a server there is always a chance of failure.

So a full backup and a make recovery should be done before.

Harry / Paula,

Thanks for the response, looks like I will just have to cross my fingers that it all goes smoothly (having taken a good backup first), I am hoping to avoid an all-nighter restoring data on Sunday evening :-)

kevin,

being that I have had some firmware load failures, I now have HP do about 80% of the upgrades, especially on production equipment. And I have them bring a replacement in case of a failure. This way I don't have to wait up to 4 hours because they are right there :-)

Harry,

HP will be doing the upgrade so I am covered in case of problems.

Is it a common occurence that a disk may fail?????????

Oh well more overtime my be heading my way :-}

Cheers,

Speak nicely to your HP Engineer and ask them to bring spare disks "Just in case".

Hi Kevin

"I'd rather be flying" ?

Pilot ?

Kevin,

A few years ago we had the firmware "upgraded" on roughly 200+ old scsi disks, and only a few failed and it wasn't due to the firmware upgrade - the drives wouldn't spin up. For that matter, I can't even remember a disk failing from an upgrade.

Just snap a few backups of your data and especially make_tape_recovery's.

Paula,

Great picture.

I took my first lesson about 18mths ago in Southend-on-Sea Essex, due to circumstances I have not resumed them as yet but hope to start in the new year.

Not sure whether to take a trip to the states and do the course there and then do the UK conversion and ILS/Night in the UK, or do the whole lot in the UK and suffer the expense.

Do you fly???

Hello,

Firmware upgrades are always a risk, but if you don't do anything silly, it should go fine.

Just do not interrupt it, else you'll have a nice dead disk.

Also, make sure no FC requests/read/write is going on... disable disks from LVM to be safe. You can also remove the fibre links to the FC hub and connect to the FC disks directly to be extra sure nothing is going FC-wise.

Should HP do that for you, you will be safe cuz if a disk fails, they'll replace it there and then if it is under warranty. So, be sure you have the nice backup or two handy if such thing happens.

HTH,
Vince

Hi Kevin

Yes I fly from Biggin Hill.

I was buzzin aroud over Southend a couple on months ago.

The USA is cheaper - I am off to Kissimmee in December for some flying. There is a branch of Cabair there.

Paula,

What do you fly? I was flying a Cessna 152, my flying was Ok but found the taxiing a bit of a task, having the brakes above the rudder pedals was a bit strange.

I will probably do the cheaper option of traveling to the USA, did you learn with Cabair or who would you recommend.

Happy flying

Kev

Hi Kev

Yes Cabair on a Piper Warrior - low wings = better vis in the turn.

The are not the cheapest but good quality instructors.
