Why two instances of ISM have different results for the same task?

Publication Date:  2014-09-19 Views:  184 Downloads:  0

Issue Description

The customer tried to remove a lun from a host through local ISM and his resoults was negative.
He tried to remove the same lun from the host through ISM via web browser and he was able to remove this lun.

After that our customer asked us:

“I would like to know why two instances of your ism software have different results for the same task. Both claim to be the same version.”

Alarm Information

without any allarms

Handling Process

In this case i sent to our customer some printscreens with how to see the full serial number related the ISM version for both situation.

In below we have these pictures like an example.

How to identify the ISM version for these 2 options (1.via web browser and 2.local) ?

Option 1:
Check the complete / full  version in web browser.

Option 2:

Please run javaws –viewer command to open the Java cache viewer, and then right click the Oceanstor application and select “Show JNLP file”, scroll down and find the info as in below picture.

Root Cause

Apparantly these 2 ISM version are  the same because our customer saw only V and R from serial number - related the ISM version  - V100R006 from entire number for the version:  Version=ISM V100R006C00SPC300

We have to show our customers "how to see"  the whole serial number (the full serial number)  related the ISM version for both situation (for local ISM  and for web browser ISM). 



In most of  cases the ISM version from “local”  is  different from ISM version from “web browser”  and is perfect normally in this situation as only one version (the most advanced version)  to be able to do the task [in our case – remove a lun from the host] .

If the versions are the same and  one version (the local one) can’t do a task [in our case – remove a lun from the host]  the second one (via web browser) also can’t do this operation.
