How to interpret inqsyminq outputWhen running inq or syminq, youll see a column titled Ser Num. This column has quite a bit of information hiding in it. Device                          Product                         Device. Name                    Type    Vendor  ID              Rev     Ser Num         CapKB. EMC     SYMMETRIX       5. BCV     EMC     SYMMETRIX       5. GK      EMC     SYMMETRIX       5. GK      EMC     SYMMETRIX       5. A2. 81        2. 88. Using the first and last serial numbers as examples, the serial number is broken out as follows 7. Last two digits of the Symmetrix serial number. Symmetrix device number. Symmetrix director number. If lt 1. 6, using the A processor. Port number on the director. Last two digits of the Symmetrix serial number. A     Symmetrix device number. Symmetrix director number. If 1. 6, using the B proccessor on board brd 1. Port number on the director. So, the first example, device 0. A, port 0 while the second example has device 0. A mapped to director 1. B, port 0. How are hypers laid out across underlying hard drives Courtsey James SpurinThe recommendation internally with the V Max is for 8 hyper splits across the disk, in testing this configuration has been proven to provide the best pormance as each lun has dedicated access to one of the disks internal queues, in essence. Disk. 1 would service part of 0. Disk. 2 would service part of 0. Disk. 3 would service part of 0. Disk. 4 would service part of 0. Disk. 5 would service part of 0. Disk. 6 would service part of 0. Disk. 7 would service part of 0. Disk. 8 would service part of 0. Therefore when device 0. You can work out the size necessary for this by dividing the size of the disk by 8, i. GB disk would be 5. GB in our case the magic number 5. Another good point to know is that also confirmed is that there is no degradation in performance when you configure these through symconfigure instead symwin as per a bin file configuration it. With regards to the ACLX setting on the directors by default the ACLX lun is presented to all directors and subsequently any host will always see t lun which can be annoying and cause confusion you can resolve this by presenting gatekeepers to the management host and then unpresenting the ACLXn from the directors. How to use a single Unix server client to run commands on various remote management servers symapi servers managing different arrays It involves 2 steps 1. On client, edit varsymapiconfignetcnfg on local Unix server client to define remote management servers. DC1SERVER    TCPIP  host. A  1. 92. 1. 68. 0. ANY                  DC2SERVER    TCPIP  host. B  1. 92. 1. 68. 1. ANY                  2. On client, connect to DC1SERVER or DC2SERVER by exporting following variables can be done either manually or via profile files export SYMCLICONNECTTYPEREMOTE export SYMCLICONNECTDC1SERVER Errors while running the commands remotely ERRORCLIENT symcfg list. The remote connection is refused. The symapi server is probably not running. SOLUTION storsrvd is not running on remote server. Start the stordaemon as below. DC1SERVER stordaemon list. Available Daemons   Currently Running. EMC Solutions Enabler Base Daemon. EMC Solutions Enabler GNS Daemon. EMC Solutions Enabler RDF Daemon. EMC Solutions Enabler Event Daemon. EMC Solutions Enabler Watchdog Daemon. EMC Solutions Enabler STP Daemon. EMC Solutions Enabler SYMAPI Server Daemon. DC1SERVER stordaemon start storsrvd. Waiting for daemon to start. This may take several seconds. DC1SERVER stordaemon list. Available Daemons   Currently Running. EMC Solutions Enabler Base Daemon. EMC Solutions Enabler GNS Daemon. EMC Solutions Enabler RDF Daemon. EMC Solutions Enabler Event Daemon. EMC Solutions Enabler Watchdog Daemon. EMC Solutions Enabler STP Daemon. EMC Solutions Enabler SYMAPI Server Daemon. ERRORCLIENT symcfg list. The remote clientserver handshake failed. Please consult symapi and storsrvd log files. SOLUTIONThis is because remote server is expecting either a securenonsecure protocol for connection. Change the parameter storsrvd securitylevel in varsymapiconfigdaemonoptions on server. Italsky Snadno A Rychle Pdf. Before change   storsrvd securitylevel   SECUREAfter change remove hash and change SECURE to NONSECURE storsrvd securitylevel   NONSECUREShutdown and start storsrvd using stordaemon command and try again. ERRORCLIENT symcfg list. The remote connection is refused. The client cannot have a newer SYMAPI version than the server. SOLUTIONIts for an obviously stated reason Solution Enabler on client is of a higher version than that on server. Check the version by running command symcli. CLIENT symcli. Symmetrix Command Line Interface SYMCLI Version V7. Edit Level 1. 75. SYMAPI Version V7. Edit Level 1. 75. DC1SERVER symcli. Symmetrix Command Line Interface SYMCLI Version V7. Edit Level 1. 05. SYMAPI Version V7. Edit Level 1. 05. ERRORCLIENT symcfg list. The trusted host file disallowed a client server connection. SOLUTIONOn remote server that is running storsrvd, check varsymapiconfignethost file and add an entry in the format FQDNofclient useridallowedfromclient example hostname. A username. Restart storsrvd daemon by runningstordaemon shutdown storsrvd and stordaemon start storsrvd. ERRORCLIENT symcfg list. The gatekeeper device while using the Base Daemon has an error Please see the Log file. CLIENT symcfg discover. This operation may take up to a few minutes. Please be patient.
