HP-UX 11.31 安裝RAC 新增共享磁碟的問題（兩種辦法）
HPUX 11.31下更改裝置名（測試透過）
個人還是推薦用第二種辦法，第一種感覺危險，因為我不太熟悉HP-UX。不知道ioinit具體用法
在HPUX(特別是HPUX 11.31,不能安裝其它多路徑軟體)下安裝ORACLE RAC時，建ASM磁碟組時有時會碰到兩個節點上儲存對映過來的磁碟磁碟機代號不一致，有時是物理路徑一致，但聚合後路徑不一致，有時甚至物理路徑也不一致，此時就需將兩個節點上的磁碟磁碟機代號修改為一致，上網找了很久，找到一篇HPUX網站上的一篇文件，將實施過程記錄下來，以備後查：
1.確認LUN ID與磁碟的對應關係，確認兩個節點磁碟的對應關係
首先找到儲存對映到主機的磁碟的LUN ID，並將兩臺主機之間相同LUN ID的磁碟對應關係找到，因為HP 11.31使用的是HP自己的多路徑軟體，如果儲存是HDS的話可以透過HDS提供的工具指令碼來找到磁碟和LUN ID的對應關係：
HPUX下Lun對應關係檢視方式如下：
請將附件的工具inqraid.hpux以二進位制模式ftp上傳到主機/tmp目錄，執行以下命令
a>cd /tmp
b>chmod +x /tmp/inqraid.hpux
c>ioscan -fun | grep -e rdisk -e rdsk | ./inqraid.hpux -CLI -fx
d>ioscan -fun | grep -e rdisk -e rdsk | ./inqraid.hpux -CLI -fx -fg

-h可以看到更多選項。。。。。。 -------------------------------------------因為沒有這個工具那麼可以使用查詢WWID來一一對應也可以
scsimgr lun_map -D /dev/rdisk/diskxx |grep WWID 這裡是關鍵，不能弄錯了，每個盤一一對應
根據命令的輸出結果可以核對出主機裝置名與儲存裝置Lun的對應關係。
scsimgr lun_map -D /dev/rdisk/diskxx |grep WWID 這裡是關鍵，不能弄錯了，每個盤一一對應
根據命令的輸出結果可以核對出主機裝置名與儲存裝置Lun的對應關係。
如果是EMC或者其它的需要找儲存廠商瞭解，如果找不到辦法就只有用最笨的辦法，一塊盤一塊盤的對映來找磁碟和LUN ID的對應關係
以下對映了5塊磁碟，儲存是EMC CX4-240,在兩個節點上磁碟與LUN ID的對應關係如下：
LUNID 節點1磁碟名 節點2磁碟名
lun 36 /dev/rdisk/disk216 /dev/rdisk/disk191
lun 37 /dev/rdisk/disk217 /dev/rdisk/disk192
lun 38 /dev/rdisk/disk218 /dev/rdisk/disk193
lun 39 /dev/rdisk/disk219 /dev/rdisk/disk194

lun 39 /dev/rdisk/disk219 /dev/rdisk/disk194

db : 10.2.0.5.0
由於RAC環境下的資料儲存空間快撐滿了，於是在儲存上劃了4個256G的LUN指定給RAC(IP1:10.1.10.56;IP2:10.1.10.57)
1、檢視各HOST下現有的磁碟路徑，並將LUN指定給HOST後，檢視指定後的磁碟路徑，對比：

2、找出新增加的磁碟路徑，找出對應磁碟機代號及WWN：
第一種方法：ioscan -funNC disk
第二種方法：根據以上4個結果集,對比出新增加的磁碟路徑，找出對應磁碟機代號及相應的WWN(eg:c22t0d2前三位應為磁碟通道，對比後四位)
第二種方法：根據以上4個結果集,對比出新增加的磁碟路徑，找出對應磁碟機代號及相應的WWN(eg:c22t0d2前三位應為磁碟通道，對比後四位)
10.1.10.56
新增加的磁碟路徑
/dev/dsk/c26t1d4
/dev/dsk/c18t1d5
/dev/dsk/c24t1d6
/dev/dsk/c32t1d7
新增加的磁碟路徑
/dev/dsk/c26t1d4
/dev/dsk/c18t1d5
/dev/dsk/c24t1d6
/dev/dsk/c32t1d7
10.1.10.57
新增加的磁碟路徑
/dev/dsk/c48t1d3
/dev/dsk/c50t1d4
/dev/dsk/c60t1d5
/dev/dsk/c48t1d6
新增加的磁碟路徑
/dev/dsk/c48t1d3
/dev/dsk/c50t1d4
/dev/dsk/c60t1d5
/dev/dsk/c48t1d6
3、根據磁碟路徑，查詢ioscan -m dsf輸出結果，找出對應磁碟機代號
10.1.10.56 對應磁碟機代號
/dev/rdisk/disk121
/dev/rdisk/disk126
/dev/rdisk/disk133
/dev/rdisk/disk139
10.1.10.56 對應磁碟機代號
/dev/rdisk/disk121
/dev/rdisk/disk126
/dev/rdisk/disk133
/dev/rdisk/disk139
10.1.10.57 對應磁碟機代號
/dev/rdisk/disk93
/dev/rdisk/disk99
/dev/rdisk/disk108
/dev/rdisk/disk116
/dev/rdisk/disk93
/dev/rdisk/disk99
/dev/rdisk/disk108
/dev/rdisk/disk116
4、找出對應磁碟機代號的唯一ID，並找出其WWN(磁碟機代號應該是字元裝置檔案)：
10.1.1.94.56
$ ll disk121 disk126 disk133 disk139
crw-r----- 1 bin sys 13 0x000025 Oct 11 13:53 disk121
crw-r----- 1 bin sys 13 0x000026 Oct 11 13:54 disk126
crw-r----- 1 bin sys 13 0x000027 Oct 11 13:56 disk133
crw-r----- 1 bin sys 13 0x000028 Oct 11 14:08 disk139
scsimgr lun_map -D /dev/rdisk/disk121 | grep WWID
scsimgr lun_map -D /dev/rdisk/disk126 | grep WWID
scsimgr lun_map -D /dev/rdisk/disk133 | grep WWID
scsimgr lun_map -D /dev/rdisk/disk139 | grep WWID
WWN的結果省略
10.1.194.57
#cd /dev/rdisk
# ll disk93 disk99 disk108 disk116
crw-r----- 1 bin sys 13 0x000015 Oct 11 13:53 disk108
crw-r----- 1 bin sys 13 0x000016 Oct 11 14:06 disk116
crw-r----- 1 bin sys 13 0x000013 Oct 11 13:50 disk93
crw-r----- 1 bin sys 13 0x000014 Oct 11 13:51 disk99
#cd /dev/rdisk
# ll disk93 disk99 disk108 disk116
crw-r----- 1 bin sys 13 0x000015 Oct 11 13:53 disk108
crw-r----- 1 bin sys 13 0x000016 Oct 11 14:06 disk116
crw-r----- 1 bin sys 13 0x000013 Oct 11 13:50 disk93
crw-r----- 1 bin sys 13 0x000014 Oct 11 13:51 disk99
scsimgr lun_map -D /dev/rdisk/disk93 | grep WWID
scsimgr lun_map -D /dev/rdisk/disk99 | grep WWID
scsimgr lun_map -D /dev/rdisk/disk108 | grep WWID
scsimgr lun_map -D /dev/rdisk/disk116 | grep WWID
WWN的結果省略
scsimgr lun_map -D /dev/rdisk/disk99 | grep WWID
scsimgr lun_map -D /dev/rdisk/disk108 | grep WWID
scsimgr lun_map -D /dev/rdisk/disk116 | grep WWID
WWN的結果省略
5、根據一一對應的WWN值，將相應WWN對應兩個節點的磁碟機代號設定成一致:
10.1.10.56
#mknod /dev/rdisk/data5disk c 13 0x000013
#mknod /dev/rdisk/data6disk c 13 0x000014
#mknod /dev/rdisk/data7disk c 13 0x000015
#mknod /dev/rdisk/data8disk c 13 0x000016
10.1.10.56
#mknod /dev/rdisk/data5disk c 13 0x000013
#mknod /dev/rdisk/data6disk c 13 0x000014
#mknod /dev/rdisk/data7disk c 13 0x000015
#mknod /dev/rdisk/data8disk c 13 0x000016
10.1.10.57
#mknod /dev/rdisk/data5disk c 13 0x000025
#mknod /dev/rdisk/data6disk c 13 0x000026
#mknod /dev/rdisk/data7disk c 13 0x000027
#mknod /dev/rdisk/data8disk c 13 0x000028
#mknod /dev/rdisk/data5disk c 13 0x000025
#mknod /dev/rdisk/data6disk c 13 0x000026
#mknod /dev/rdisk/data7disk c 13 0x000027
#mknod /dev/rdisk/data8disk c 13 0x000028
6、設定兩個節點對應磁碟機代號路徑的許可權：
#chown oracle:oinstall /dev/rdisk/data5disk
#chown oracle:oinstall /dev/rdisk/data6disk
#chown oracle:oinstall /dev/rdisk/data7disk
#chown oracle:oinstall /dev/rdisk/data8disk
#chown oracle:oinstall /dev/rdisk/data5disk
#chown oracle:oinstall /dev/rdisk/data6disk
#chown oracle:oinstall /dev/rdisk/data7disk
#chown oracle:oinstall /dev/rdisk/data8disk
7、以ORACLE使用者檢驗讀寫許可權
$dd if=/dev/zero f=/dev/rdisk/data5disk count=10 count=1024
$dd if=/dev/zero f=/dev/rdisk/data5disk count=10 count=1024
8、在其中一節點上為ASM磁碟組新增磁碟
export ORACLE_SID=+ASM3
sqlplus / as sysdba
export ORACLE_SID=+ASM3
sqlplus / as sysdba
alter diskgroup DATADG add disk '/dev/rdisk/data5disk';
alter diskgroup DATADG add disk '/dev/rdisk/data6disk';
alter diskgroup DATADG add disk '/dev/rdisk/data7disk';
alter diskgroup DATADG add disk '/dev/rdisk/data8disk';
alter diskgroup DATADG add disk '/dev/rdisk/data6disk';
alter diskgroup DATADG add disk '/dev/rdisk/data7disk';
alter diskgroup DATADG add disk '/dev/rdisk/data8disk';
(注意: 檢查diskgroup新增前後的對比.
select a.GROUP_NUMBER, a.name, a.path, b.NAME
from v$asm_disk a,
v$asm_diskgroup b
where a.GROUP_NUMBER = b.GROUP_NUMBER
select a.GROUP_NUMBER, a.name, a.path, b.NAME
from v$asm_disk a,
v$asm_diskgroup b
where a.GROUP_NUMBER = b.GROUP_NUMBER
)
