1、查看机型：Sun的小型机的机型都在面板上写着有，如NETRA T 1125，
还有比如ultra 5,ultra 10等等。
2、查看cpu个数 (错误，不正确，因为sun中的top命令不能完全看到所有的cpu情况，与HP用法也不一样)
# top
CPU states: 99.3% idle, 0.1% user, 0.6% kernel, 0.0% iowait, 0.0% swap
表示只有一个cpu
正确方法：
用dmesg |grep cpu
便可以看到正确的 cpu个数了。
3、查看内存
#dmesg |grep mem
mem = 2097152K (0x80000000)
avail mem = 2087739392
4、查看磁盘的个数
#vxdisk list
DEVICE TYPE DISK GROUP STATUS
c0t0d0s2 sliced - - error
c0t0d0s7 simple c0t0d0s7 rootdg online
c1t0d0s2 sliced - - online
c1t1d0s2 sliced smpdg2 smpdg online
c1t2d0s2 sliced smpdbdg1 smpdbdg online
c2t0d0s2 sliced - - online
c2t1d0s2 sliced smpdg1 smpdg online
c2t2d0s2 sliced smpdbdg2 smpdbdg online
5、如何查看文件系统
#df -k
Filesystem kbytes used avail capacity Mounted on
/dev/dsk/c0t0d0s0 4032142 1050675 2941146 27% /
/proc 0 0 0 0% /proc
fd 0 0 0 0% /dev/fd
/dev/dsk/c0t0d0s6 7304977 29 7231899 1% /home
/dev/dsk/c0t0d0s5 4032142 402929 3588892 11% /opt
swap 3418392 32 3418360 1% /tmp
/vol/dev/dsk/c0t6d0/informix
201730 201730 0 100% /cdrom/informix
/dev/vx/dsk/smpdg/smpdg-stat
1055 9 941 1% /smpwork
/dev/vx/dsk/smpdg/lv_smp
17336570 128079 17035126 1% /sms
6、查看卷组、逻辑卷的位置
#cd /dev/vx/dsk/
比如smpdg等等都在该目录下了，然后再进入某个卷组目录就可以看到该卷组下
面的逻辑卷了。
7、如何创建卷组、逻辑卷、文件系统
A、创建smpdg逻辑卷组(假设现在是将c1t1d0 和c1t2d0两块物理磁盘来创建smcpdg逻辑卷组)
vxdisksetup -i c1t1d0 (格式化物理磁盘)
vxdisksetup -i c2t1d0
vxdg init smpdg smpdg1=c2t1d0 (将物理磁盘加入到逻辑卷组smpdg)
vxdg -g smpdg adddisk smpdg2=c1t1d0
然后再来创建逻辑卷、文件系统
vxassist -g smpdg -U fsgen make lv_smp 17200m layout=nolog smpdg1
vxassist -g smpdg mirror lv_smp layout=nostripe smpdg2
newfs -C -f /dev/vx/rdsk/smpdg/lv_smp
假设现在的一台机器上挂接到/sms
mkdir /sms
chown smp:smp /sms
vxvol -g smpdg startall
mount /dev/vx/dsk/smpdg/lv_smp /sms
umount /sms
vxvol -g smpdg stopall
vxdg deport smpdg
然后再在第二台机器上挂接到/sms
mkdir /sms
chown smp:smp /sms
vxdg import smpdg
vxvol -g smpdg startall
newfs -C -f /dev/vx/rdsk/smpdg/lv_smp
mount /dev/vx/dsk/smpdg/lv_smp /sms
umount /sms
备注：以上是创建一个共享的文件系统
往往由于smpdg要分配给某一个应用来使用，所以需要再来创建一个个逻辑机运行
时挂接的文件系统：
vxassist -g smpdg -U fsgen make smpdg-stat 2m layout=nolog smpdg1
vxassist -g smpdg mirror smpdg-stat layout=nostripe smpdg2
newfs /dev/vx/rdsk/smpdg/smpdg-stat
B、创建smpdbdg逻辑卷组
创建卷组：
vxdisksetup -i c1t2d0
vxdisksetup -i c2t2d0
vxdg init smpdbdg smpdbdg1=c1t2d0
vxdg -g smpdbdg adddisk smpdbdg2=c2t2d0
vxassist -g smpdbdg -U fsgen make smpdbdg-stat 2m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror smpdbdg-stat layout=nostripe smpdbdg2
newfs /dev/vx/rdsk/smpdbdg/smpdbdg-stat
创建逻辑卷：
vxassist -g smpdbdg -U gen make lv_rootdbs 128m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_rootdbs layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_logdbs 300m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_logdbs layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_phydbs 100m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_phydbs layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_tempdbs 1000m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_tempdbs layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_svcchunk1 2000m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_svcchunk1 layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_svcchunk2 2000m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_svcchunk2 layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_svcchunk3 2000m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_svcchunk3 layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_recchunk1 2000m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_recchunk1 layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_recchunk2 2000m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_recchunk2 layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_recchunk3 2000m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_recchunk3 layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_recchunk4 2000m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_recchunk4 layout=nostripe smpdbdg2
vxassist -g smpdbdg -U gen make lv_recchunk5 1700m layout=nolog smpdbdg1
vxassist -g smpdbdg mirror lv_recchunk5 layout=nostripe smpdbdg2
C、附逻辑卷的属性
vxedit -g smpdg -v set user=smp group=smp lv_smp
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_rootdbs
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_logdbs
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_phydbs
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_tempdbs
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_svcchunk1
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_svcchunk2
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_svcchunk3
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_recchunk1
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_recchunk2
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_recchunk3
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_recchunk4
vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_recchunk5
备注：在SUN的机器中在给逻辑卷付属性的时候，等于用chown、chmod来作。
8、如何删除卷组
其实也就是去激活和倒出的过程，然后再来对物理磁盘重新格式化就完了。
vxvol -g smpdbdg stopall
vxdg deport smpdbdg
vxdisksetup -i c1t0d0
vxdisksetup -i c2t1d0
......
这样做了之后就不会再有/dev/vx/smpdbdg目录了。
9、如何建立共享卷组
在第一台机器上先建立卷组，假设已经建设好卷组smpdg,现在要在第二台机器上建立共享卷组smpdg,
则先在的一台机器上将smpdg去激活、并且倒出smpdg：
smcp01>vxvol -g smpdg stopall
smcp01>vxdg deport smpdg
再来在第二台机器上激活、导入smpdg:
smcp02>vxdg import smpdg
smcp02>vxvol -g smpdg startall
切换后对用以下三个命令进行查看是否切换成功：
vxdg list //用于查看逻辑卷组的信息
vxdisk list //用于查物理磁盘的信息
vxprint -vt //用于查看所有卷的信息
10、如何查看磁盘的大小
方法一：
#format
