fdisk can help.
Here is a little hack I named "lunsizes" that assumes up to 26 mounted
LUNs and "friendly names" (/dev/mapper/mapth<x>):
#!/bin/bash
# find LUNs in /dev/mapper and list in bytes and GiB
ls /dev/mapper/mpath[a-z] >/dev/null 2>&1
if [ $? != 0 ]; then # no LUNs found
echo "No LUNs found in /dev/mapper/mpath*"
exit 1
fi
echo -e "LUN \tBytes \t~GiB"
for nextLUN in /dev/mapper/mpath[a-z]; do
bytes=`fdisk -l $nextLUN 2>/dev/null | grep "Disk $nextLUN" | awk
'{print $5}'`
let GB=bytes/1024/1024/1024
echo -e "$nextLUN \t$bytes \t$GB"
done

[LINUX-390] SCSI/FCP disk size
Sent by:
Linux on 390 Port <[email protected]>
Hello List,
Is there a way to find out the size of a native SCSI device attached via
FCP channel? I do not see lszfcp or lsscsi having an option that lets you
see the size of the disk you have attached to a VM.
Thanks,
Thang Pham
