Collect support data for your storage array using ThinkSystem System Manager.
a.
Select Support › Support Center › Diagnostics.
b.
Select Collect Support Data.
c.
Click Collect. The file is saved in the Downloads folder for your browser with the name,
support-data.7z.
4.
Ensure that no I/O operations are occurring between the storage array and all connected hosts.
For example, you can perform these steps:
◦ Stop all processes that involve the LUNs mapped from the storage to the hosts.
◦ Ensure that no applications are writing data to any LUNs mapped from the storage to the
hosts.
◦ Unmount all file systems associated with volumes on the array.
The exact steps to stop host I/O operations depend on the host operating
system and the configuration, which are beyond the scope of these
instructions. If you are not sure how to stop host I/O operations in your
environment, consider shutting down the host.
Possible data loss — If you continue this procedure while I/O operations
are occurring, the host application might lose access to the data because
the storage is not accessible.
5.
If the storage array participates in a mirroring relationship, stop all host I/O operations on the
secondary storage array.
6.
Wait for any data in cache memory to be written to the drives.
The green Cache Active LED on the back of each controller is on when cached data needs to
be written to the drives. You must wait for this LED to turn off.
