AIX中以併發模式掛載vg 要想以併發模式掛載VG 必須要有/usr/sbin/gsclvmd 這個進程,而些進程是安裝HACMP 的必要的檔案集bos.clvm.enh,同時gsclvmd 也是由HACMP 啟動的,多個節點掛載並發VG 的時候是以併發模式掛載的,當然我們在有gsclvmd 服務的時候也可以手工以手工方式掛載,如下所示:# ps -ef | grep gsc root 6553738 14680086 0 18:13:58 pts/0 0:00 grep gsc root 16973844 4784366 0 17:45:02 - 0:00 /usr/sbin/gsclvmdvaryon -c datavg# lsvg datavgVOLUME GROUP: datavg VG IDENTIFIER: 00f670fd00004c0000000130b18686a0VG STATE: active PP SIZE: 256 megabyte(s)VG PERMISSION: read/write TOTAL PPs: 3383 (866048 megabytes)MAX LVs: 512 FREE PPs: 742 (189952 megabytes)LVs: 79 USED PPs: 2641 (676096 megabytes)OPEN LVs: 58 QUORUM: 9 (Enabled)TOTAL PVs: 17 VG DESCRIPTORS: 17STALE PVs: 0 STALE PPs: 0ACTIVE PVs: 17 AUTO ON: noConcurrent: Enhanced-Capable Auto-Concurrent: DisabledVG Mode: ConcurrentNode ID: 2 Active Nodes: 1MAX PPs per VG: 130048MAX PPs per PV: 1016 MAX PVs: 128LTG size (Dynamic): 256 kilobyte(s) AUTO SYNC: noHOT SPARE: no BB POLICY: relocatablePV RESTRICTION: nonehost1:hdisk4 00f670f4b1515565 datavg concurrenthdisk5 00f670f4b151570f datavg concurrenthdisk6 00f670f4b1515898 datavg concurrenthdisk7 00f670f4b1515a0f datavg concurrenthdisk8 00f670f4b1515b85 datavg concurrenthdisk9 00f670f4b1515cfe datavg concurrenthdisk10 00f670f4b1515e83 datavg concurrenthdisk11 00f670f4b1515ffe datavg concurrenthdisk12 00f670f4b151a635 datavg concurrenthdisk13 00f670fd03402eb2 datavg concurrenthdisk14 00f670fd03403ee6 datavg concurrenthost2:hdisk4 00f670f4b1515565 datavg concurrenthdisk5 00f670f4b151570f datavg concurrenthdisk6 00f670f4b1515898 datavg concurrenthdisk7 00f670f4b1515a0f datavg concurrenthdisk8 00f670f4b1515b85 datavg concurrenthdisk9 00f670f4b1515cfe datavg concurrenthdisk10 00f670f4b1515e83 datavg concurrenthdisk11 00f670f4b1515ffe datavg concurrenthdisk12 00f670f4b151a635 datavg concurrenthdisk13 00f670fd03402eb2 datavg concurrenthdisk14 00f670fd03403ee6 datavg concurrent
