Last update: 11-06-2021

Symptoms

After Acronis Cyber Infrastructure update to version 4.0, disk blink option became not available - greyed out, although this funcion was working well before update, e.g.:

Storage controllers are being detected correctly by ledctl utility when checking via node's CLI, e.g.:

[root@aci-node-01 ~]# ledctl --list-controllers
/sys/devices/pci0000:00/0000:00:1f.2 (AHCI)
/sys/devices/pci0000:00/0000:00:03.2/0000:06:00.0 (SCSI)
/sys/devices/pci0000:00/0000:00:11.0/0000:07:00.0 (SCSI)

Cause

Issue in version 4.0 of the product, fixed permanently in the scope of Acronis Cyber Infrastructure 4.5 release.

Solution

Update cluster to the latest version

As a workaround for version 4.0, it is possible to use CLI commands, for example for /dev/sdm disk to start/stop disk device blinking, should be executed from the corresponding node under 'root' user:

[root@aci-node-01 ~]# /usr/libexec/vstorage-ui-agent/bin/blink.sh -p /dev/sdm -s start
Matching drive is /sys/class/block/sdm
New location state for /sys/class/block/sdm was setted by enclosure

[root@aci-node-01 ~]# /usr/libexec/vstorage-ui-agent/bin/blink.sh -p /dev/sdm -s stop
Matching drive is /sys/class/block/sdm
