2. Back up the storage array’s configuration database using SANtricity System Manager.
If a problem occurs during this procedure, you can use the saved file to restore your configuration. The
system will save the current state of the RAID configuration database, which includes all data for volume
groups and disk pools on the controller.
◦ From System Manager:
a.
Select Support
› Support Center › Diagnostics.
b. Select Collect Configuration Data.
c. Click Collect.
The file is saved in the Downloads folder for your browser with the name, configurationData-
<arrayName>-<dateTime>.7z.
◦ Alternatively, you can back up the configuration database by using the following CLI command:
save storageArray dbmDatabase sourceLocation=onboard contentType=all
file="filename";
3. Collect support data for your storage array using SANtricity System Manager.
If a problem occurs during this procedure, you can use the saved file to troubleshoot the issue. The system
will save inventory, status, and performance data about your storage array in a single file.
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.
