I was using user data to create an EC2 instance, and the HTTPD server was operational through user data. However, when I was restarting the instance and then encountered a 502 gateway error, I performed a status check. After that, I found that the HTTPD server was not running. I restarted it, and it started working again through the terminal. If I have 50 servers, and I need to restart them, do I have to start each one individually from the terminal, or is there another method? I have implemented a load balancer.
you can do it using ansible

Hi Prashant
Question number 72 how to scan the disk
using echo "- - -">/sys/scsi_host/host0/scan in this what is mean by " - - - "
The "- - -" String: This string is actually a set of three values separated by spaces, and each value corresponds to a specific SCSI address component:
The first - is a placeholder for the SCSI channel on the controller. The - acts as a wildcard meaning "all channels".
The second - is for the SCSI target ID, which is usually the address of a device on the SCSI bus. Again, - here means "all targets".
The third - is for the LUN (Logical Unit Number), which represents a logical unit of a SCSI device. Using - means "all LUNs".
Hi @Prashnt sir Can you please share or upload the slide (pdf) for this .
