1、查看機型:SUn的小型機的機型都在面板上寫著有,如NETRA T 1125, 還有比如utra 5,utra 10等等。 2、查看cpu個數 (錯誤,不正確,因為sun中的top命令不能完全看到所有的cpu情況,與HP用法也不一樣) #top CPU states: 99.3% idle, 0.1% user, 0.6% kernel, 0.0% iowait, 0.0% swap 表示只有一個cpu 正確方法: 用dmesg grep cpu 便可以看到正確的 cpu個數了。 3、查看內存 #dmesg grep mem mem = 2097152K (0x80000000) avail mem = 2087739392 4、查看磁盤的個數 #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、如何查看文件系統 #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、查看卷組、邏輯卷的位置 #cd /dev/vx/dsk/ 比如smpdg等等都在該目錄下了,然後再進入某個卷組目錄就可以看到該卷組下面的邏輯卷了。 7、如何創建卷組、邏輯卷、文件系統 A、創建smpdg邏輯卷組(假設現在是將c1t1d0 和c1t2d0兩塊物理磁盤來創建smcpdg邏輯卷組) vxdisksetup -i c1t1d0 (格式化物理磁盤) vxdisksetup -i c2t1d0 vxdg init smpdg smpdg1=c2t1d0 (將物理磁盤加入到邏輯卷組smpdg) vxdg -g smpdg adddisk smpdg2=c1t1d0 然後再來創建邏輯卷、文件系統 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 假設現在的一台機器上掛接到/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 然後再在第二台機器上掛接到/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 備注:以上是創建一個共享的文件系統 往往由於smpdg要分配給某一個應用來使用,所以需要再來創建一個個邏輯機運行時掛接的文件系統: 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、創建smpdbdg邏輯卷組 創建卷組: 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 創建邏輯卷: 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、附邏輯卷的屬性 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 備注:在SUN的機器中在給邏輯卷付屬性的時候,等於用chown、chmod來作。 8、如何刪除卷組 其實也就是去激活和倒出的過程,然後再來對物理磁盤重新格式化就完了。 vxvol -g smpdbdg stopall vxdg deport smpdbdg vxdisksetup -i c1t0d0 vxdisksetup -i c2t1d0 ...... 這樣做了之後就不會再有/dev/vx/smpdbdg目錄了。 9、如何建立共享卷組 在第一台機器上先建立卷組,假設已經建設好卷組smpdg,現在要在第二台機器上建立共享卷組smpdg,則先在的一台機器上將smpdg去激活、並且倒出smpdg: smcp01>vxvol -g smpdg stopall smcp01>vxdg deport smpdg 再來在第二台機器上激活、導入smpdg: smcp02>vxdg import smpdg smcp02>vxvol -g smpdg startall 切換後對用以下三個命令進行查看是否切換成功: vxdg list //用於查看邏輯卷組的信息 vxdisk list //用於查物理磁盤的信息 vXPrint -vt //用於查看所有卷的信息 10、如何查看磁盤的大小 方法一: #format 然後選擇盤的代號,回車進入下一級菜單,再選inquiry,就得到該盤的大小信息,比如: Vendor: FUJITSU ProdUCt: MAN3184M SUN18G Revision: 1502 注意:format是一個功能強大的磁盤診斷工具。 方法二: #cd /opt/SUNWexplo/bin/ 運行explorer得到磁盤的信息包,是一個目錄,進入該目錄,就發現有一個disks目錄,進入該目錄發現有一個diSKINfo文件,用如下命令看各個磁盤 的大小: 0: rmt/0ln HP C1537A L706 62#
