Once SYMCLI is installed the below table lists all common commands that can be used using the symcli command interface.

symmaskdb commands

init

create and initialises a device masking database. On completion, the database device cannot be written to by the operating system.

Note: This command only needs to be run once otherwise all SAN configuration is lost backup backups up the database to a specified file restore restore a database file remove removes the meta member devices

list database lists for each symmetrix fibre director which devices in a symmetrix system a WWN can access

symmaskdb -sid 516 list database -output XML

list devs (-wwn) lists all devices accessible to an HBA on a specified symmetrix system and all directors that access each device

list assignment (-dev) List the HBA assignments to devices list capacity (-host) Lists the capacity of devices assigned to a particlur host

symdev commands

listlist available devices

symdev list -inventory


-v list detailed information of a deviceshow <symdevname> display meta device information

sympd commands

listlists 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).

list -vcm lists all the physical devices in the device masking database

symcfg commands list -v lists whether the symmetrix director has device masking turned on

list -address -fa -available all lists all fibre directors in a symmetrix system and which devices they can access

symcfg -sid xxx list -address -fa 4c -p 1 -available list -sa all lists all fibre directors (FA) in a symmetrix system

list -sa 15D -v

lists detailed information on a FA port

symcfg list -RA all -sid 516 -switched symcfg -dir all list –sid 516

-application list list applications using the symmetrix

symcfg list -applications -sid xxx

-connections list

list host connections to the array

symcfg list -connections symcfg list -connections -sorthost symcfg list -connections -capacity -sid 516

symmask commandsadd devs add a device to the list of devices that a WWN can access in the database remove devs remove a device from the list of devices that a WWN can access in the database


delete deletes all access rights for a WWN in the database replace allows one HBA to replace another set lockdown sets or clears the fibre channel ID lockdown set visibility sets or clears visibility for noncontiguous LUNS set lunoffset sets or clears a LUN base/offset skip for noncontiguous LUNS. set heterogeneous sets or clears heterogeneous host inform with distinctive attributes rename changes the AWWN for the specified WWN in the database and login history table

refresh

causes the symmetrix system to refresh its WWN related memory tables with the contents of the database

If you update the VCMDB you must run this command to see your changes

discover hba discovers the HBA on the host and assigns AWWN to the login history table entries for thoses WWNs that are not set

list logins Lists foreach fibre director which hosts and HBAs are logged into the symmetrix. (displays the login history table contents)

list hba lists WWNs of the fibre HBAs on this host.

symconfigure commands -sid <sid> -f <filename> verify verify that we have access to the symmetrix and we can make changes -sid <sid> -f <filename> preview confirm that the syntax is correct -sid <sid> -f <filename> prepare -sid <sid> -f <filename> commit commit the changes to the database

control and log files locations /symapi/db/symapi_db.bin default symapi database file /symapi/config/netcnfg lists the network services available from that host


/symapi/config/optionsthe options file contains behavior parameters that can be set to critically change default behavior of SYMCLI operations, SYMAPI calls and their control actions

/symapi/config/symavoid identifies devices to skip over when looking for devices /symapi/config/gkavoid identifies devices not chosen as gatekeepers /symapi/config/inqfile lists devices to be added to the symapi database /symapi/log/symapi-<date>.log logfile for symcli.symapi functions, calls, activities

Common commands

VCMDB

initialize the VCMDB

# symmaskdb -sid xxx init -f newinit.db

Note: This command only needs to be run once otherwise all SAN configuration is lost, also make sure the database is backed up regularly.

backup the VCMDB # symmaskdb -sid xxx -file <filename> backup restore the VCMDB # symmaskdb -sid xxx -file <filename> restore

refresh the database

# symmask -sid xxx refresh

Note: Remember any changes to the VCMDB have to be uploaded to the symmetrix memory, otherwise you will not see your changes.

list the database # symmaskdb -sid xxx list database list a specific device # symmaskdb -sid xxx -dev 0029 list assignment -v

FA Ports List currently configured FA port settings (this is used primary for HP systems)

# symcfg -sa <##|all> [-p <#>] list -v

List currently visable devices on a FA port # symcfg -sid xxx -FA 15C -address list


Disk Devices

list all devices within the array # symdev list # inq

list a specific device within the array # symmaskdb -sid xxx -dev 0029 list assignment -v

add access to the symmetrix devices

# symmask -sid xxx -wwn 5000020001f2 -dir 15c -p 0 add devs 087,088,089

dir = director portp = port number on the director port

Note: the devices are symmetrix devices ID's not LUN ID's. Also this is know as LUN masking.

remove access from the symmetrix devices # symmask -sid xxx -wwn 5000020001f2 remove devs 0029,002A list devices available assigned to a specific host # symmaskdb -sid xxx -host 5000020001f2 list capacitydisplay meta devices # symdev show <symdevname>

HBAregister the HBA with the VCMDB # symmask discover hba List HBAs in local host # symmask list hba -v List HBAs to FA port logins # symmask -sid xxx list logins

Build file contentsMeta devices files Form meta from dev 0004, config-striped stripe_size=1920;

add dev 0005 to meta 0004; add dev 0006 to meta 0004; add dev 0007 to meta 0004; add dev 0008 to meta 0004;

The run the following:

# symconfigure -sid xxx -f meta.txt preview# symconfigure -sid xxx -f meta.txt prepare


# symconfigure -sid xxx -f meta.txt commit

HBA/SYMCLI solaris recomendations/etc/system * For EMCset sd:sd_max_throttle=20set scsi_options=0x7f8set sd:sd_io_time=0x3c* End EMCset semsys:seminfo_semmni=600set semsys:seminfo_semmns=600set semsys:seminfo_semume=600set semsys:seminfo_semmnu=600set shmsys:shminfo_shmmax=524288set shmsys:shminfo_shmmni=600


sd_max_throttle – The sd_max_throttle variable sets the maximum number of commands that the SCSI sd driver will attempt to queue to a single HBA driver. The default value is 256. This variable must be set to a value less than or equal to the maximum queue depth of each LUN connected to each instance of the sd driver. If this is not done, then commands may be rejected because of a full queue condition and the sd driver instance that receives the queue full message will throttle down sd_max_throttle to 1. This obviously will result in degraded performance. The variable is set in the /etc/system file as follows:

set sd:sd_max_throttle=20

sd_io_time – The sd_io_time variable is command time out value. Setting this time out value to 120 seconds will prevent the host from issuing warning messages while non-disruptive operations are performed on the disk array. For example, in a EMC Symmettrix power path environment this variable can be set to 0x3C (60 seconds). As with the sd_max_throttle value, this is set in the /etc/system file. Using the EMC value in an example:

set sd:sd_io_time = 0x3C

scsi_options – The value scsi_options is a setting for SCSI options included as outlined in the bit meaning table above. Solaris 7 default SCSI settings are for the maximum Ultra Wide Speed. Since the /etc/system file can also affect other disks in the system, consider the effects of implementing the scsi_options=0x7F8 mask on the other disks. You might consider the bus level or device level setpoints as we discussed above rather than a system wide setting. An example entry in the /etc/system file would be:

set scsi_options=0x7F8
