# "asg perf" command does not show output when MDPS is enabled on Scalable Platforms

**Product**: Maestro HyperScale Firewall  
**Version**: R81 (EOS), R81.10 (EOS), R81.20  
**OS**: Gaia  
**Last Modified**: 2025-01-16

## Symptoms

- The "`asg perf`" command on a Security Group does not show any output - the Gaia OS prompt appears immediately after entering the command and pressing the Enter key.
- When running the "`mac_verifier`" and other commands on a Security Group, the output may show the error message "`mount of /sys failed: device or resource busy`".
- The "`distutil verify -v`" command on a Security Group returns "`verification failed`".
- The "`g_allc "mount -l | grep sysfs"`" command on a Security Group shows multiple mounts of "`sysfs`".
- These issues started after enabling the MDPS feature ( [sk138672](https://support.checkpoint.com/results/sk/sk138672)).

## Cause

A mounting issue of the filesystem `sysfs` may occur when enabling the MDPS feature.

## Solution

This problem was fixed. The fix is included starting from:

- [Check Point Quantum R82](https://support.checkpoint.com/results/sk/sk181127)
- [Jumbo Hotfix Accumulator for R81.20](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.20/Default.htm) starting from Take 41
- [Jumbo Hotfix Accumulator for R81.10](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.10/Default.htm) starting from Take 131
- [Jumbo Hotfix Accumulator for R81](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81/Default.htm) starting from Take 99
- [Jumbo Hotfix Accumulator for R80.40](https://sc1.checkpoint.com/documents/Jumbo_HFA/R80.40/Default.htm) starting from Take 211

**Important Note** - After installing this Jumbo Hotfix, when MDPS plane separation is enabled, in the context of the Management plane, the directory _/sys/class/net/_ now shows interfaces that belong to the Data plane, although it should show interfaces that belong to the Management plane.

**If you choose not to upgrade, this workaround is available:**

**Important** - Schedule a maintenance window.

1. Connect to the command line on the Security Group.
2. If your default shell is Gaia gClish, go to the Expert mode:

`expert`

3. Back up this file on all Security Group Members:

`g_all cp -v /etc/profile.d/mdpsenv.sh{,_BKP}`

4. Edit this file:

`vi /etc/profile.d/mdpsenv.sh`

5. Remove these lines:
   1. `/usr/bin/mount sysfs 1>/dev/null 2>&1`
   2. `/usr/bin/umount sysfs 1>/dev/null 2>&1`

6. Save the changes in the file and exit Vi editor.
7. Copy the modified file to all Security Group Members:

`asg_cp2blades /etc/profile.d/mdpsenv.sh`

8. Reboot all Security Group Members:

`reboot -b all`
