解决solaris不支持多个lun的方法
我得机器配置dell6400，adaptec的perc2 raid 卡，外加一个dell 221的阵列，机器内部8块
73G硬盘，外部14块73G硬盘，总容量1T多，系统sol2.7x86,perc2的raid卡化了22个
container，solaris2.7只能认识8个lun，郁闷。。。。。
手动修改/kernel/drv/sd.conf文件，一个lun只支持15个target，不用多写，具体修改如下
# more /kernel/drv/sd.conf

touch /reconfigure
reboot
然后认到了22个container，好像sun的网站提供sd.conf文件的补丁，我试了，但是不行
sparc的机器也会有此问题，解决如下
8 LUNS with Solaris 2.7/E250/A1000/RAID 6.1.1 Update 2
Thanks to Andreas Sinderman (who responded immediately to the ssa-managers
mail) and Mark Reid at Sun (who responded to my service call).
Andreas had it mostly right. The Tpatch (T106925-03) coupled with the other
required configuration file changes fixed things (I got the Tpatch from Mark).
Solaris 7 doesn't support more than 16 LUNS.
In addition to the Tpatch, you need to have the following:
* Appropriate entries in /kernel/drv/sd.conf -- manually type them in (like
I did) or run add16luns.sh from the Tools directory on the Raid Manager
software cd.
* create/edit /kernel/drv/glm.conf to have:
device-type-scsi-options-list =
"Symbios StorEDGE A1000", "lsi-scsi-options",
"Symbios StorEDGE A3000", "lsi-scsi-options",
"SYMBIOS RSM Array 2000", "lsi-scsi-options";
lsi-scsi-options = 0x407f8;
* change the /etc/osa/rmparams to have 16 MaxLuns instead of 8:
System_MaxLunsPerController=16
All this and boot -r. I found that the /dev/dsk links for disks 8 and up were
not created at boot time, but were created as LUNS using these disk numbers
were created.

我没有测试过，如果可以，请告诉大家方法吧
