安裝VA磁盤陣列時,必須首先format磁盤陣列,具體步驟如下:
VA7100/VA7110
1.通過串口執(zhí)行vfpfmt
2.執(zhí)行dsp –s 查看VA信息
3.如果VA是與switch相連,要執(zhí)行mgr –t 2 –c 1/2 將private修改為public
4.執(zhí)行mgr –S 2 –c 1/2,將速率修改為2GB
5.初始化完成后注意通過更改磁盤陣列的RAID級別(armmgr –C)
6.如果用光纖switch,要在前改變VA7100的loop topology to fabric
7.劃分LUN時,先建一個20MLUN0,保持這個LUN不要使用。
8.劃分LUN后進行一次重起測試
9.在創(chuàng)建VG前,要查明哪條路徑是主路徑(在機器背面看,VA7100左邊的控制器c1是主控制器)
10.創(chuàng)建VG時要保證主路徑的盤在前面
a.Using a terminal connected directly to VA, issue the command vfpmgr –ds {on|off}. Then an “ioscan” will display the LUN which are still visible when the secondary controller is disabled
b.Using the “SDM” v1.05, the command “armmgr –S {on|off} will also do the same function.
VA7400/VA7410
1.首先給主盤箱加電(斷開主盤箱與子盤箱連接光纖)
2.通過串口執(zhí)行vfpfmt
3.初始化完成后關閉主盤箱
4.連接主盤箱與子盤箱之間的光纖
5.分別給子盤箱加電
6.全部硬盤加電完成后給主盤箱加電
7.VA7400會自動將其余子盤箱的硬盤格式化為520byte/sector
8.在子盤箱硬盤格式化完成之前不要繼續(xù)其他操作(約需30-60分鐘)
9.如果用光纖switch,要在前改變VA7100的loop topology to fabric
10.初始化完成后注意通過更改磁盤陣列的RAID級別(armmgr –C)
11.劃分LUN時,先建一個20MLUN0, 保持這個LUN不要使用(第一次做的時候就忘記了)
12.幫助客戶劃分LUN,保證VA7400的兩個group的負載均衡(和客戶商量, 按VA7400的Service Manual操作)
13.劃分LUN后注意進行一次重起測試
14.在創(chuàng)建VG前,要查明哪條路徑是主路徑(VA7400左邊的控制器c1是groupA的主控制器,VA7400右邊的控制器c2是groupB的主控制器)
a.Using a terminal connected directly to VA, issue the command vfpmgr –ds {on|off}. Then an “ioscan” will display the LUN which are still visible when the secondary controller is disabled
b.Using the “SDM” v1.05, the command “armmgr –S {on|off} will also do the same function.
15.創(chuàng)建VG時要保證主路徑的盤在前面!!!
二、操作
16.關機時最好先執(zhí)行armmgr –s shut 或vfpmgr –s shut,然后再關閉電源開關
17.Service之前請先備份armdsp –a信息
18.更換硬盤之前先執(zhí)行armdsp –a觀察磁盤陣列狀態(tài),是否有其它報錯存在
19.若發(fā)現(xiàn)異常報錯,不要急于重起,與響應中心聯(lián)系
