Symmetrix CLI cheat sheet First the Solution enabler software has to be installed which can be obtained from powerlink.emc.com. The should be unzip/untarred and the emc_install program should be run. You need to license the product and then run the following command to discover the connected symmetrix: # /usr/symcli/bin/symcfg discover # /usr/symcli/bin/symcfg list Once installed the below table lists all common commands that can be used using the symcli command interface. symmaskdb commands create and initialises a device masking database. On completion, the database device cannot be written to by the operating system. init Note: This command only needs to be run once otherwise all SAN configuration is lost backup restore remove list database list devs (-wwn) list assignment (-dev) list capacity (-host) symdev commands list -v list show -noport list sympd commands lists the symmetrix devices that are accessed through fibre channel and shows their controlling director, TID, LUN, device number and serial number. Also shows which device holds the device masking database (VCM). lists all the physical devices in the device masking database list available devices detailed information of a device display meta device information list available devices backups up the database to a specified file restore a database file removes the meta member devices lists for each symmetrix fibre director which devices in a symmetrix system a WWN can access lists all devices accessible to an HBA on a specified symmetrix system and all directors that access each device List the HBA assignments to devices Lists the capacity of devices assigned to a particlur host

lists whether the symmetrix director has device masking turned on lists all fibre directors in a symmetrix system and which devices they can access lists all fibre directors (FA) in a symmetrix system lists detailed information on a FA port list applications using the symmetrix list host connections to the array
add a device to the list of devices that a WWN can access in the database remove a device from the list of devices that a WWN can access in the database deletes all access rights for a WWN in the database allows one HBA to replace another sets or clears the fibre channel ID lockdown sets or clears visibility for noncontiguous LUNS sets or clears a LUN base/offset skip for noncontiguous LUNS. sets or clears heterogeneous host inform with distinctive attributes changes the AWWN for the specified WWN in the database and login history table causes the symmetrix system to refresh its WWN related memory tables with the contents of the database
refresh If you update the VCMDB you must run this command to see your changes discover hba list logins list hba symconfigure commands -sid -f verify -sid -f preview -sid -f commit verify that we have access to the symmetrix and we can make changes confirm that the syntax is correct (since we use a mapping files) commit the changes to the database discovers the HBA on the host and assigns AWWN to the login history table entries for thoses WWNs that are not set Lists foreach fibre director which hosts and HBAs are logged into the symmetrix. (displays the login history table contents) lists WWNs of the fibre HBAs on this host.

Also this is know as LUN masking.
