Hi

Help needed, when i connect to our MSA1000 Array, and issue the commands, we dont get all the output display, only partion or sometime missing output shown below...

Here the ouput missing Disk101 thru 106???

show disks

Disk1 160 MB/s 3
Disk107 1,07 0,08 300.0 GB 160 MB/s 3

If we ran the show disks again we got another different output....

We see this behaviour sometimes when using multiple CLI commands in a script. It seems to overrun the buffer on the terminal emulator. Solution was to enter one command, wait until the output finishes and then enter the next one.

Hopefully this helps.

Tried that, like you suggested, one CLI command at a time, the output still the same. :(

What settings are you using when connecting to the controller?

Hmmmm not sure at this point in time. When was the last time you rebooted the MSA and at what firmware level is it at?

Well, so far we haven't reboot the MSA1000 for awhile but only the server (rp4440) which connected to it for regular OS patching. We was able to access it before, just not recently. :(

What you are seeing is definitely some kind of "drop out". Are you using the proper cable for the MSA1000?

I know,you are right, something is dropping out... we are using the RJ45Z cable which come with the MSA1000.

Not sure i any setting i can do to increase the buffer some where of if i have a bad cable. .will try out and let u know the result, thanks for the help.

Do you have access to any other terminal emulators? KeaTerm PowerTerm, etc

See if you can download a "trial" version and see if it works. If it doesn't then it might point at the cable.

Hi have you tried the show tech_support ? Also you mentioned patching the server but not the controller firmware level.

Hi Guys!!!

Thanks for all the suggestion. Finally we found the root cause of this problem. It was due to the bad serial port that our RJ45Z connection. After we used a different serial port, it works fine now.
