EMC和HDS存储在HACMP配置添加Custom Disk Methods

HA切换时磁盘挂载慢的问题
HACMP配置中需要对EMC和HDS存储的配置添加Custom Disk Methods

EMC配置（EMC Host Connectivity Guide for IBM AIX）
For IBM Fibre Channel configurations with PowerPath 3.0.3
and higher:
–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/Symmetrix/bin/emcpowerreset
or
–/usr/lpp/EMC/CLARiiON/bin/emcpowerreset
Break reserves in parallel =true
Method to make the disk available = MKDEV
*For IBM SCSI configurations with PowerPath 3.0.3, 3.0.4:
–Disk Type (PdDvLn field from CuDv) =
disk/pseudo/power
Method to identify ghost disks = SCSI2
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 =true
Method to make the disk available = MKDE

HDS配置（HDLM手册有说明）
Adding Custom Disk Methods
1. From the SMIT window, display the Add Custom Disk Methods window.
Choose the following sequence of menu items to display this window:
smitty
--> Communications Applications and Services
 --> HACMP for AIX
  --> Extended Configuration
    --> Extended Resource Configuration
     --> HACMP Extended Resource Configuration
      --> Configure Custom Disk Methods
and finally choose Add Custom Disk Methods.
2.  In the Add Custom Disk Methods window, specify the items as shown
below:
The items to be set and setting contents are shown below:
– When a Fibre Channel connection is used with HACMP
Change the custom disk method settings as described below. The
description includes information about the items and contents of the
settings.
-->Disk Type (PdDvLn field from CuDv)
* When a HP XP series is used:
  [disk/fcp/HP]
* When a Thunder 9500V series, Lightning 9900V series (excluding
HP XP series), Hitachi USP (excluding HP XP series), Universal
Storage Platform V/VM (excluding HP XP20000 and HP XP24000),
or Hitachi AMS/WMS series is used:
  [disk/fcp/Hitachi]
-->Method to identify ghost disks
  [SCSI3]
-->Method to determine if a reserve is held
  [/usr/DynamicLinkManager/cluster/dlm_hacmp_gdisk_reserve_check]
-->Method to break a reserve
  [TARGET]
-->Break reserves in parallel  
  [false]
-->Method to make the disk available  
  [MKDEV]
3.  When you finish specifying the settings, click the OK button.
4.  HACMP Verification and Synchronization.
