Understanding the Expansion Process
Understanding the expansion procedure helps ensure a smooth expansion.
Figure 13-1 shows the flowchart for expanding LUN capacity.
Table 13-7 describes each step in detail.
Procedure |
Description |
|---|---|
Perform a pre-expansion check. |
Before expanding LUN capacity, make sure that the storage system meets expansion requirements. Obtain and record necessary information including the IP address of the application server that uses the LUN, the WWN of the LUN, or the host LUN ID. |
Locate the LUN to be expanded. |
Before expanding LUN capacity, confirm information about the LUN that carries service data to ensure a successful expansion. |
Expand LUN capacity on the storage system. |
Expand the LUN online to the required capacity. |
Expand storage space for the application server. |
After the expansion, scan for disks on the application server to detect and use the expanded LUN. |
