Write a shell script to check the NetApp storage health

 

You can use the NetApp ONTAP CLI commands within a shell script to check the health of your NetApp storage system. Here is a basic script that checks the health status of your NetApp storage:

Sample Shell Script to Check NetApp Storage Health

#!/bin/bash

# Define the NetApp cluster management IP and login credentials

CLUSTER_IP="192.168.1.100"

USERNAME="admin"

PASSWORD="password"

# Check for cluster health status

echo "Checking cluster health status..."

health_status=$(sshpass -p "$PASSWORD" ssh "$USERNAME@$CLUSTER_IP" "system health status show")

# Check for hardware issues

echo "Checking for hardware issues..."

hardware_issues=$(sshpass -p "$PASSWORD" ssh "$USERNAME@$CLUSTER_IP" "system node run -node * -command environment status")

# Check for disk health

echo "Checking disk health..."

disk_health=$(sshpass -p "$PASSWORD" ssh "$USERNAME@$CLUSTER_IP" "storage aggregate show -fields state")

# Output the results

echo "Cluster Health Status:"

echo "$health_status"

echo ""

echo "Hardware Issues:"

echo "$hardware_issues"

echo ""

echo "Disk Health:"

echo "$disk_health"

echo ""

# Optionally, log this information to a file

log_file="netapp_health_check_$(date +'%Y%m%d').log"

{

    echo "Cluster Health Status:"

    echo "$health_status"

    echo ""

    

    echo "Hardware Issues:"

    echo "$hardware_issues"

    echo ""

    

    echo "Disk Health:"

    echo "$disk_health"

    echo ""

} > "$log_file"

echo "Health check complete. Results saved to $log_file."

Explanation:

1. sshpass: This tool allows you to pass the password automatically for the SSH command. You may need to install sshpass first by running sudo apt-get install sshpass.

2. Cluster health check: The system health status show command checks the general health of the NetApp cluster.

3. Hardware issues check: The environment status command shows hardware health, such as fans, power supplies, etc.

4. Disk health check: The storage aggregate show -fields state command shows the state of the storage aggregates (whether online, offline, etc.).

5. Logging: The script logs the output to a file with a date-based filename.

You should replace CLUSTER_IP, USERNAME, and PASSWORD with your actual NetApp cluster management IP address and login credentials.
