Orphaned Storage
Hi, I'd like to find orphaned storage across DMX and VMAX.
Not interested in reclaiming thin space, but to find devices that are either in a Storage Group that are not in Masking Views, or other situations where devices could appear to be in use from some perspectives, or DMX devices that are mapped / masked to host WWNs that are no longer there using login info etc, and similar situations.
There must be many people who have tackled this in many ways. I can see approaches to collect the info that I want, but if folk have good ways of collecting this, to save reinventing the wheel, techniques like that would be greatly appreciated?
Many thanks.

Minor efficiency update to the script (avoid processing the same WWN multiple times):
for wwn in $(symaccess -sid 00 list logins | grep ^[0-9] | cut -c 1-16 | sort | uniq); do
echo " checking wwn $wwn"
symaccess -sid 55 -type initiator list -wwn $wwn > /dev/null 2>&1
if [ $? -ne 0 ];then
echo "$wwn not in any IG"
fi
done

Symcli handles many of the checks you are after natively. Here are some examples to get you started...
Thin devices that are no not mapped to an FA:
symdev list -thin -noport
Thin devices that are not in a Storage Group:
symdev list -thin -notinsg
Tdevs no bound to a pool:
symdev list -tdev -unbound
Devices Mapped to a port but not in an MV (not valid for DMX):
symaccess list no_assignment
List WWN's that are in the login history table, but not currently logged in:
symaccess -sid 55 list logins | grep -v "Yes Yes"
To check WWN's that are in the login history table, but not in an IG, put a couple of commands together:
for wwn in $(symaccess -sid 00 list logins | grep ^[0-9] | cut -c 1-16); do
echo " checking wwn $wwn"
symaccess -sid 55 -type initiator list -wwn $wwn > /dev/null 2>&1
if [ $? -ne 0 ];then
echo "$wwn not in any IG"
fi
done
