How to defeat host mismatch with HP MSA1500 drive?

Question

Python

Greetings!
There is an HP MSA1500 shelf, 2 hosts are connected to it via FC network and HBA:
1. W2K8 Ent SP2 6.0.6002 32-bit
2. W2K8 R2 Std 6.1.7601 64-bit
What was done.
1. Create a logical disk in the free space of the array

2. Set up access to the created disk in SSP (Selective Storage Presentation)

3. Save the configuration and go to Disk Management server 1 and notice the new disk that has appeared there

4. Initialize it

5. Create a new partition

6 We go to the Disk Management server 2. Press F5 and the disk appears there automatically.

7. Now we try to create some folder on this disk (on server 2).

8. And if I understand everything correctly, then the folder should be displayed in the corresponding disk on the server 1. We go in, update ...

Empty???
9. Now we are trying to create a folder on server 1

10. Open the disk in the explorer of server 2 and make sure that the situation is identical, only vice versa.
Why is this happening? What am I doing wrong? Maybe a glitch due to different versions of Windows?
UPD: I tried to connect the disk to a couple of W2K3 servers, they, in turn, saw only the folder created on server 1. This raises the assumption that the disk of server 2 is not working correctly. I continue experiments ...

Answer 1

To answer this question, you need to explain the whole concept of OOP
. I advise you to read about OOP in Python
in fact sheet1.cell_value(0,0) is a function that returns a value, and since this value does not refer to any of the "variables", it immediately removed by the garbage collector

Comrade, that's not how things are done. If you need access to this disk directly from both servers, then you need to dig somewhere in the direction of Cluster Shared Volume. And so it will not work - there will be constant conflicts when modifying metadata between servers, since each server believes that it has exclusive ownership of this disk.
