To solve this issue, do the following:
1. Check that the device is physically connected properly. If the wire connection is detached, the system may show errors like:
No such device
2. Check that you have the permission or privilege to use the mkfs command.
3. Check that the device and device driver are on-line. If the device or device driver is offline, turn it on-line.
-
Check that the device is on-line. That is, the LUNs are in connection. Enter:
# vxdisk list
If the device is offline, make the device on-line. Enter:
# vxdisk -f init disk_name
The command above turns on-line the device specified in the disk_name argument.
-
Check that the device driver is on-line. Enter:
# fcmsutil /dev/td0
If the device driver is offline, make the driver on-line. Enter:
# isnf -e
