MSL 2024

I would like to know if there are some known problems with the firmware for MSL 2024?
I had no problem with the 4 of MSLs we have until I upgraded the firmware from 1.80 to 1.91 an then to 2.40.
The problems are errors with the robot.
Looks like I'll have to downgrade.

Any known problems and solutions?

Re: MSL 2024

Hello Marko,

There are currently no known issues with the firmware revision 2.40. Please send me you the exact error codes that you encounter after upgrading to 2.40 from 1.80. Also(as a note), the first official HP release following 1.80 was 2.00 (since 1.91 is only a bridge code). I you still need to downgrade, please try 2.00 first. Please keep in touch with me, and I should be able to help you work through this issue.
Regards,
Tom Gregory, HP

And another support ticket attached from another MSL2024.

Re: MSL 2024

Hello Marko,

I don't have a rar decoder. Please use zip files. Thank you. What is the Serial Number of your MSL 2024?

Thanks.

Re: MSL 2024

1st MSL Controller Serial # : DEC062500U
2nd MSL Controller Serial # : DEC06230WW

Other serial # are in the support ticket files.
I have 2 more MSL - but with the same problems so... here it is.

Re: MSL 2024

Marko,

I am still studying your LTT files. Thank you. I do notice that your LTO Gen 2 drives a at an older firmware revision (S39W). The newest version is S54W. Since S39W, this firmare has been release S3BW, S53W and the latest is S54W. I don't know if this is could be related to your issue, but up grading these drives will definately clear other known issues.

Re: MSL 2024

Marko,

I see now that you are already at S54W.
Sorry to trouble you with my last reply.

Re: MSL 2024

Marko,

Because of your problem statement,

"I had no problem with the 4 of MSLs we have until I upgraded the firmware from 1.80 to 1.91 an then to 2.40"

I assumed that you always used the path of 1.80 to 1.91 (non-functional bridge firmware) to 2.40. I am in the process of testing this upgrade path to see if I am able to duplicate the issues that you have reported. The purpose of the 1.91 bridge firmware was to allow downgrading of firmware to 1.80 or 1.70 versions. This is not a recommended procedure (from HP), but we wished to provide this path. The versions 1.70 and 1.80 did not include the ability to program new versions of the product's robotic firmware. Each bundle of firmware includes the correct version of robotic firmware. The bridge firmware 1.91 contains the robotic download function and loads the robotic firmware required for 1.70 or 1.80 firmware. After loading 1.91 followed by 2.00 or 2.40, each version (>1.91) is able to load the correct robotic firmware. In both LTT support tickets, I see the report "invalid robotic code".

When upgrading firmware, if the 1.91 bridge was not loaded, then the new version 2.00 or 2.40 would have invalid robotic code. If the same version (2.00 or 2.40) was loaded twice the correct robotic firmware would be loaded.

Please reload the 2.40 firmware into your MSL G3 and check if you have restored functionality.

Thanks. TOm

Re: MSL 2024

Here is a bit of additional information:
Checking on the front panel display (OCP) or the Remote Managment Interface (RMI)with your web browser, both the library firmware and the associated robotics firmware are listed. The following are the expected combinations:
1.70/1.30e
1.80/1.30e
1.91/1.30e
2.00/1.60e
2.40/1.66e

If any of your libraries display a different combination than listed above please let me know. For instance, the combination 2.40/1.30e would indicate that firmware was upgraded directly from 1.80 to 2.40. In this case, you need to load 2.40 a second time and then the correct result should be displayed as(2.40/1.66e). Other combinations may indicate a download failure caused by an unknown factor (maybe a bug or power loss or ...).

Regards,
Tom

Re: MSL 2024

Tkanks for the replays Tom.
I'll check the OCP and let you know, but sadly I don't have the time to do this this week (a lot of other work). I'll do it on Monday.
Thanks again.

Re: MSL 2024

I've seen this issue before.
Just re-flash your firmware to 2.40

Then you won't have that message any more.

Re: MSL 2024

Sorry for taking me so long... work

Tom,
I checked on my OCP and my ver. is expected: 2.40/1.66e
So this is ok.

Andrew,
I did upgrade fw again for 2 times - nothing.
Then I downgraded to 1.91 and again to 2.40.
Sadly nothing better.

I get different error codes:
B2 00 12
B0 71 32
F1 00 32
83 02 00
83 B0 00
8D 07 00
8D 07 31
F1 00 4D

When I run the Wellness Test I get the message:
Unit offline
Mail slot disabled

At POST of the server the MSL ind the Drive don't get listed unless I change the Drive ID - which is what I do.

I am running one more desperate fw upgrade right now.

Re: MSL 2024

Hello Marko,

The firmware that you reported 2.40/1.66e is the one you should be using.

Regarding the failures of the Wellness Test, the failures that you report are normal. The Wellness Test requires that the mailslot should be enabled before the test can run. The mailslot can be enabled in the configuration screen of RMI.

I have requested a better description of the errors that you sent today. I will forward these when I have more information.

Regarding your statement,
"At POST of the server the MSL ind the Drive don't get listed unless I change the Drive ID - which is what I do."

This sounds like there may be a conflict with the your application. I do not think that your library is defective. I plan your problems with other team members and reply again later today. Thank you.

Re: MSL 2024

Hello Tom,

I can not enable the mailslot - it stays disabled no mater how many times I try.

I don't use any application.
I am just using L&TT (latest ver.)
This has no affect on listing the MSL and the Drive at POST. It should be listed under SCSI devices.

The fact that I have to change the ID to list it on POST and that I can not enable the mailslot gets me thinking that there might be a problem with the controller of the MSL or with the FW of the controller.

Sadly I can not get the 1.80 ver. of the FW to check my thoughts.
So if anyone has 1.80 fw ver. - please attach.

Re: MSL 2024

Marko,

How are you attempting to disable the mailslot? I would suggest using the RMI (Remote Manager Interface). This connects using an IP address and an browser on your network. You must have admistrator access.
Check the mailslot enabled box and then select the Apply Selections button on the right hand side of the screen.

Tom

Re: MSL 2024

Marko,

I meant to write 'enable the mailslot' instead of 'disable the mailslot'.

I think you may have a configuration issue with your jukeboxes after you upgraded from 1.80 to 2.40. Quotes the release notes follows:
"IMPORTANT: Several configuration settings are reset to defaults if the library is upgrading from library firmware versions 1.70 or 1.80.
â ¢ Mailslot is set to disabled
â ¢ Drive 1 SCSI ID is set to 4
â ¢ Drive 2 SCSI ID is set to 5
â ¢ Master Drive (Library LUN hosted by) is set to Drive 1
â ¢ Drive 1 power is set to on
â ¢ Drive 2 Power is set to on
â ¢ Library Mode is set to Automatic
â ¢ Autoload Mode is disabled
â ¢ Loop Mode is disabled"

You should use either the OCP (front panel) or the RMI to reset your configurations to the correct settings if they have been changed by the firmware upgrade.

This firmware upgrade is very important to the proper operation of the library. You should use it and future firmware upgrades as a means to improve operations of your product. Unfortunately, I didn't understand the most likely cause of your problems until now.

If you are not able to resolve your current set of issues by restoring configurations, then you should contact your local HP support office. I am sorry that you have encountered this much trouble. Future firmware releases will not cause this type or any other types of customer problems.

Re: MSL 2024

The nature of the issues you are experiencing are typically caused by attempting to use the 1.91 bridge (non-functional) version of firmware. Since you have already upgraded to 2.4 from teh bridge, you should not be experiencing this issue.

I would advise calling support and getting a temporary password for LTT to permit a downgrade of both AL and drive firmware to 1.80... then bridge, then update to latest version of firmware.

Please also note that drive and autoloader firmware ALWAYS need to be upgraded togehter or you will incur issues with library operation.

"When I run the Wellness Test I get the message:
Unit offline
Mail slot disabled"

The mailslot might be causing issue if you have the incorrect magazine in position 1. There is only 1 magazine with a mailslot and if this is placed in any other position then the first position in the library the mailslot will not work and the library will not identify a mailslot being active.

Re: MSL 2024

After another failed try of upgrading FW on the library and tape drive I got this 2 similar messages in event viewer:

The device 'Unknown Medium Changer' disappeared from the system without first being prepared for removal.

The device 'HP Ultrium 2-SCSI SCSI Sequential Device' disappeared from the system without first being prepared for removal.

I claimed a new library without the drive.
The new library came with the new FW. I tryed to use the new library with the "old" drive and everything works OK.

Is there a probability that there is something wrong with loading of the FW - a bug in FW load procedure? I can not imagine that I am doing something wrong here. I upgraded many tape devices till now with no problems.

Re: MSL 2024

The messages you report are normal during a firmware upgrade. After the library receives the firmware it will take itself and the drive offline and then install the new firmware. That takes long enough that the OS notices the devices are missing.

Is everything working correctly for you now? It sounds like it from your message.

Firmware updates form firmware older than 2.00 always take two downloads but usually that is all. For some reason it sounds like yours took more than 2 before finally getting the robot updated.

Firmware download problems are considered very serious and HP is working on making it as robust and simple as possible. There should not be any more updates that require two downloads.

Re: MSL 2024

Hello Curtis

Not everything is working correctly for me, yet.
I still have 3 MSL's to fix.

"For some reason it sounds like yours took more than 2 before finally getting the robot updated."
I got the new FW on the drive and on the MSL, but they did not want to work together - I got this curious robotic error.

"The messages you report are normal during a firmware upgrade. After the library receives the firmware it will take itself and the drive offline and then install the new firmware."
I started the upgrade in the evening and then looked at it in the morning. So the library had the whole night to get upgraded. I did this more times.
But then in the morning I could see that the FW is up to date - but I couldn't get the mail slot enabled, I couldn't open the left or the right magazine... I gor the error.

I am afraid that I will have to claim 3 more new librarys without the drive.

Re: MSL 2024

Two questions I'm not clear on:

1) "I got the new FW on the drive and on the MSL, but they did not want to work together - I got this curious robotic error."

What curious robotic error? The only thing I can find in your message is mention of the OS reporting a new "Unknown Medium Changer" but not reporting a new drive. The drive didn't change firmware so the OS is still seeing exactly the same drive it saw before but that would be the drive from the library.

Is there some other "curious robotic error"? Something in the library logs?

2) Unable to configure the mailslot. I've seen comments about this earlier in the string but can't pick out enough details to help. Can you please post details of exactly what procedure your are following and what happens? There are only a couple of problems I can reproduce: front panel or web browser incorrect password, and not pressing "Enter" on the front panel "Enable Mailslot?" question or "Submit" on the web interface. From your description it sounds like you are seeing something other than those problems.

The only other issue I know of with enabling a mailslot is that neither the front panel or web interface will allow configuration changes while the library is performing an operation so if a move or test is in progress then you can't enable the mailslot.

Re: MSL 2024

Marko,

Have you used the web interface at all? Some settings are easier to configure using a web browser.

To use the web browser connect your library to the network. DHCP is the default and hopefully will work for you.


Use the front panel to get the DHCP assigned network address then use your web browser to open a connection to the library.

Logging in as user does not require a password but will not allow changing configuration settings.

To log in as administrator you need to use the library front panel to set an administrator password and then you can use that password on the web interface.
