ISCSI阵列能用于HACMP+ORACLE+RAC环境中吗（已解决）
最近一个客户买了2台570，为节省开支，决定用3年前买的EQUALLOGIC阵列来连接HACMP+ORACLE；
我说，ISCSI阵列可以用在HACMP上，但是ORACLE RAC就不见得支持了；ISCSI+RAC的认证只限于LINUXWIN平台，建议用热备吧....Blabla说了一大堆.....
客户对非常迷信RAC，非得用RAC不可；而SI已经折腾了好些天了，HA是装上去了，但是安装CRS的时候总报错，提示什么设备不可访问之类的东西....SI的工程师找了N多资料，GOOGLE了几百次，还是没找到类似的案例.....
于是，DELL找到我，要我帮忙。
我跑过去一看，检查PV的RESERVE_POLICY，结果没这属性；lsvg居然半天没出来，varyoffvg也失败......
既然人家都找到我了，我总得做点什么，于是我跟他们说，虽然ISCSI+RAC+HACMP没有成功案例，但是我愿意测试一把.....
回到公司，GOOGLE和百度半天，真的从没有人做过类似的案例；直接问DELL的支持，他们说也没有.....
上metalink，里面提到ISCSI+RAC+HACMP没通过认证，即使是主流的NETAPPEMC等ISCSI阵列：
=============================================================================================
For iSCSI, Oracle has made the statement that, as a block protocol, this technology does not require validation for single instance database. There are many early adopter customers of iSCSI running Oracle9i and Oracle Database 10g. As for Oracle RAC, Oracle has chosen to validate the iSCSI technology (not each vendor's targets) for the 10g platforms - this has been completed for Linux and Windows. For Windows we have tested up to 4 nodes - Any Windows iSCSI products that are supported by the host and storage device are supported by Oracle. We don't support NAS devices for Windows, however some NAS devices (eg NetApp) can also present themselves as iSCSI devices. If this is the case then a customer can use this iSCSI device with Windows as long as the iSCSI device vendor supports Windows as an initiator OS. No vendor-specific information will be posted on Certify.
=============================================================================================
虽然官方说可能不支持，我也只好硬着头皮上了
测试环境
p630 LPAR*2
vmware+equallogic simulator
100M LAN
装系统、打补丁、找软件.....忙了2天，环境是搭建好了，HA也配好了，可是有时VG起不来，并提示NIM BLOCK的错误，我想这应该是ISCSI LUN对应的心跳磁盘IO负载太高了，尝试着调慢，还是不行.....
问各位坛友，有谁接触过这样的案例？到底能不能做？
悬赏20分那:lol

IBM* PowerHA* (formerly High Availability Cluster Multiprocessor (HACMP*)) for AIX*, V5.3 and
V5.4.1 expands support to include the following dual node models of the IBM System Storage N
series:
N5300 (2869-A20, 2869-G20)
N5600 (2868-A20, 2868-G20)
The N series models are designed to provide fast data access, simultaneous multiprotocol support,
expandability, ability to upgrade, and low maintenance requirements.
Please refer to the following table for support details.
IBM System Storage**
(models noted above)
AIX V5.3
AIX 6.1
PowerHA V5.3
PowerHA # IZ19054
AIX 5300-07
RSCT 2.4.5.4

AIX 5300-07
RSCT 2.4.5.4
PowerHA # IZ22290
AIX 6100-00-02
RSCT 2.5.0.0
**Requires Data ONTAP version 7.2.3 or above.
Note: iSCSI support requires APAR IZ25443 for PowerHA 5.4.1 and APAR IZ25554 for
PowerHA 5.3 (These APARs are not yet generally available. Please contact IBM Support for an
interim fix.)
Restriction Note: Multipath I/O via iSCSI is not supported at this time. IBM intends to remove
this restriction in a future product update.

怎么解决的？期待heroman007 发表于 2011-12-6 10:08
这么老的贴也被翻出来了目前为止，RAC FOR AIX好像还没发布支持ISCSI阵列的兼容报告吧不过是可以安装的。把必要的包和参数全部设定好就OK，不过安装的时候CRS会莫名其妙起不来...浏览2570
