### Find Host/Channel/Id/Lun of device
### On systems with large number of connected perhepials, we need to find proper HCIL from lsscsi, f.x.
### [2:0:10:0]   tape    HP       Ultrium 6-SCSI   25MW  /dev/st6
### As awk's Field Separator use three characters '] [ :' , but we have to double escape brackets 
### Ref. https://www.gnu.org/software/gawk/manual/html_node/Command-Line-Field-Separator.html
HCIL="$(lsscsi | awk 'BEGIN {FS="[\\]|\\[|:]"} / +cd\/dvd +HP +Ultrium/ { print $2, $3, $4, $5; exit }')"
