Connect to a Linux server over SSH by running the following command in the terminal: ```bash ssh root@ ``` 1. Download `HW Watcher`: ```bash wget https://storage.yandexcloud.net/baremetal-support-tools/support/hwcheck ``` 1. Add the root user permissions to run the downloaded executable file: ```bash chmod u+x hwcheck ``` 1. Run the downloaded utility: ```bash ./hwcheck ``` As a result, the report files will be saved to an archive: ```text ... Save data to archive: hwcheck_my-sample-server-_2025-05-27_20-31-04.tgz ``` 1. To view status reports for individual server disks, unpack the archive by specifying its name: ```bash tar -xvzf ``` 1. In the `drive` directory, see the list of disk status report files: ``` ls ./drive/ -l ``` Result: ```text total 24 -rw-r--r-- 1 root root 8957 May 27 20:31 sda-smartctl -rw-r--r-- 1 root root 8957 May 27 20:31 sdb-smartctl ``` 1. Look up the contents of the report file for the disk of interest. The disk device ID is specified in the file name: ```bash cat ./drive/sda-smartctl ``` Among other things, a table of the disk's [SMART](https://en.wikipedia.org/wiki/Self-Monitoring,_Analysis_and_Reporting_Technology) attribute values will be displayed: ```text ...

Copy the report from the server to your local computer by running this command in the local computer terminal: ```bash scp root@:/root/ ./ ``` This will save the report file to the current directory on your local computer. 1. [Create](https://center.yandex.cloud/support/tickets/create) a request to support. In your request, describe the issue with the server in detail and attach the saved archive with the report. #### See also {#see-also} * [Analysis of Yandex BareMetal server disk status](../../concepts/smart-disk-analysis.md) * [Replacing a disk in a RAID array](switch-raid-member.md)
