To obtain the external IP address of a specific node in a Dell EMC PowerScale cluster, the platform engineer can use commands that provide detailed node information.
Using 'isi status -q':
Function:
The isi status -q command displays a concise list of nodes along with their IDs and external IP addresses.
Syntax:
Running this command from any node in the cluster will provide the required information.
Output:
Includes node IDs, IP addresses, and status information.
Why Other Options Are Incorrect:
Option B (isi network external view):
Provides information about the external network interfaces but may not directly map node IDs to IPs.
Option C (isi status -p):
Displays the cluster status in a parsed format but may not include IP addresses.
Option D (isi network subnets list):
Lists subnets configured on the cluster but does not provide node-specific IP addresses.
Details the usage of isi status -q to retrieve node information.
Usage Example:
# isi status -q
Node | LNN | Health | IP Address | ...
------+-----+--------+-----------------+-----
Node2 | 2 | Good | 192.168.1.102 | ...
Best Practices:
Use the isi status command family for quick status checks.
Combine with other commands for comprehensive monitoring.
