How to map the devices to FA port (if devices are not contiguous, then you would need a new line for each device – you can’t use commas to separate them)
# cat map_devs
map dev 0200:0202 to dir 08b:0, starting lun=06e;
map dev 0200:0202 to dir 09b:1, starting lun=06e;
OR
map dev 0200 to dir 08b:0, lun=06e;
map dev 0200 to dir 09b:1, lun=06e;
map dev 0201 to dir 08b:0, lun=06f;
map dev 0201 to dir 09b:1, lun=06f;
# symconfigure -sid 5678 -file map_devs prepare
Rule of pair mapping (rule of 17):
On DMXs – Ports are [3,4,7,8,9,10,13,14][a-d]. a to d, b to c with rule of 17 and ports opposed. So 3a:0 will be partnered with 14d:1. 4b:1 will be paired with 13c:0.
On VMAXs – Ports are [5-12][e-h]. e to e, f to f, g to g, h to h with rule of 17. so 5f:0 will be 12f:0, 8g:0 will be 9g:0 and so on.
How to unmap devices from FA ports (if devices are not contiguous, then you would need a new line for each device – you can’t use commas to separate them)

How to map the devices to FA port (if devices are not contiguous, then you would need a new line for each device – you can’t use commas to separate them)
# cat map_devs
map dev 0200:0202 to dir 08b:0, starting lun=06e;
map dev 0200:0202 to dir 09b:1, starting lun=06e;
OR
map dev 0200 to dir 08b:0, lun=06e;
map dev 0200 to dir 09b:1, lun=06e;
map dev 0201 to dir 08b:0, lun=06f;
map dev 0201 to dir 09b:1, lun=06f;
# symconfigure -sid 5678 -file map_devs prepare
Rule of pair mapping (rule of 17):
On DMXs – Ports are [3,4,7,8,9,10,13,14][a-d]. a to d, b to c with rule of 17 and ports opposed. So 3a:0 will be partnered with 14d:1. 4b:1 will be paired with 13c:0.
On VMAXs – Ports are [5-12][e-h]. e to e, f to f, g to g, h to h with rule of 17. so 5f:0 will be 12f:0, 8g:0 will be 9g:0 and so on.
How to unmap devices from FA ports (if devices are not contiguous, then you would need a new line for each device – you can’t use commas to separate them)
