# Troubleshooting for Imaging Commvault Grid Nodes When Media Fails to Mount

Follow the troubleshooting instructions given below:

1. Troubleshooting USB Drive Issues

   If imaging via a USB drive fails due to media not mounting, check the following:

   a. USB Creation Method – If creating USB drive using a Linux/HSX client, make sure to pause ransomware protection before executing the dd command.

   b. Boot Mode – Verify that the node is in UEFI boot mode. Nodes in Legacy BIOS mode cannot be imaged using a USB drive.

2. Troubleshooting ISO Mounting via Remote Interface

   If using an ISO mounted through a hardware vendor's remote interface, ensure the remote interface is set up as a dedicated port (iLO, IPMI, iDRAC, IRMC, CIMC) and not a shared port.

3. USB Drive Not Detected in BIOS

   If the BIOS does not recognize the USB drive when attempting to boot:

   - Check the USB drive size. Some hardware vendors struggle to detect 16GB USB drives in the BIOS/pre-boot environment due to vendor limitations.

   - Try using an 8GB or 32GB USB drive — whichever size is sufficient to accommodate the ISO being used.
