A.2 SP Switch Pool Size Settings
Two important switch parameters were changed from their default values:
rpoolsize and spoolsize. To check the current values, enter:
lsattr -El css0
and look for rpoolsize and spoolsize. 512 KB per processor is the default
size. Both values should be increased if high I/O traffic is expected on the SP
Switch. To increase both values to 5 MB (as applied in all of our scenarios),
enter:
/usr/lib/methods/chgcss -l css0 -a spoolsize=5242880 -a rpoolsize=5242880
For the changes to take effect, the SP nodes must be rebooted.
