understanding the emc syminq command and what it tells you about devices

so here is a syminq command output

eudt0206:root / > ./var/tmp/SYMCLI.depot/SYMCLI/SYMCLI/SYMCLI/V6.4.0/bin/syminq

let us break it down further - here we have a total of 5 EMC symmetrix disks, with multipathing;

that are also being used under vxvm;

/dev/vx/rdmp/c4t9d5 M(4) EMC SYMMETRIX 5771 0400721000 35692800

/dev/vx/rdmp/c4t13d7 M(4) EMC SYMMETRIX 5771 040072D000 35692800

to find out the device ID, look at the 6th column;

/dev/vx/rdmp/c4t9d4 M(4) EMC SYMMETRIX 5771 040071D000 35692800

040071D000 breaks down as
04 are the last 2 digits of the serial number of the Symmetrix array/frame
0071D is the Symmetrix device ID number
000 is always 000 and doesn't have meaning

Also - GK stands for Gatekeeper devices, and the M stands for Mirror (with the 4 indicating that it is a 4 way mirror)
