实战：HACMP5.3配置EMC concurrent资源组

硬件平台：P570、EMC CX500

软件平台：AIX5300-05-04、HACMP5.3、PowerPath 4.5


两台P570做双机集群，配置concurrent资源组共享CX500上的磁盘

故障现象：一个节点的concurrent vg正常激活，另外一个节点concurrent vg没有正常激活


解决方法：

1．添加第三方磁盘支持
# smitty hacmp-> Extended Configuration.-> Extended Resource Configuration. ->
HACMP Extended Resources Configuration. -> Configure Custom Disk Methods.
-> Add Custom Disk Methods.

Disk Type (PdDvLn field from CuDv) = disk/pseudo/power
Method to identify ghost disks = SCSI3
Method to determine if a reserve is held = SCSI_TUR
Method to break a reserve = /usr/lpp/EMC/CLARiiON/bin/emcpowerreset
Break reserves in parallel = false
Method to make the disk available = MKDEV


# chmod +x /usr/lpp/EMC/CLARiiON/bin/emcpowerreset



2．配置cfgscsi_id

ftp bin方式上传cfgscsi_id 到目录 /usr/sbin
# chmod +x /usr/sbin/cfgscsi_id


# /usr/es/sbin/cluster/utilities/claddcustom -t event -n'cfgscsi_id' -I'Set correct scsi id on EMC CLARiiON pseudo devices.' -v'/usr/sbin/cfgscsi_id'



3．配置HACMP事件

# /usr/es/sbin/cluster/utilities/clchevent -O'node_up' -s'/usr/es/sbin/cluster/events/node_up' -b 'cfgscsi_id' -c '0'

# /usr/es/sbin/cluster/utilities/clchevent -O'node_down' -s'/usr/es/sbin/cluster/events/node_down' -b 'cfgscsi_id' -c '0'
