tsm 备份正在修改的文件 (SERialization)

今天碰到了在线备份的文件不能备份的问题，解决方法如下：

tsm: TSM>update co sms_domain SMS_SET SMS_14D SERialization=shrdy
ANR1532I Backup copy group STANDARD updated in policy domain SMS_DOMAIN, set
SMS_SET, management class SMS_14D.
 
tsm: TSM>activate policyset sms_domain SMS_SET
 
Do you wish to proceed? (Yes (Y)/No (N)) Y
ANR1514I Policy set SMS_SET activated in policy domain SMS_DOMAIN.

Then backup the modifying files, it is okay.

But I met some errors as below:

I checked the dsmerror.log:

09/04/12   16:38:18 ANS0326E This node has exceeded its maximum number of mount points.
09/04/12   16:38:18 ANS1228E Sending of object '/sms/log/20120904/sms_itemnow.log' failed
09/04/12   16:38:18 ANS0326E This node has exceeded its maximum number of mount points.
09/04/12   16:38:18 ANS1802E Incremental backup of '/sms/log/*' finished with 18 failure

---------------

Then I will upadate the node "maxinum mount point allowed"

When I executed the follow command:

tsm: TSM>update node a05gsmsapp1a maxnummp=2
ANR2150E UPDATE NODE: Node TESTNODE is currently accessing the server.
ANS8001I Return code 12.

Then I used command to check:

tsm: TSM>q session
 
  Sess Comm.  Sess     Wait   Bytes   Bytes Sess  Platform Client Name        
Number Method State    Time    Sent   Recvd Type          
------ ------ ------ ------ ------- ------- ----- -------- --------------------
      
71,629 Tcp/Ip IdleW  18.1 M  32.8 K   1.2 K Node  AIX      TESTNODE       
71,630 Tcp/Ip RecvW  14.8 M     364 119.8 M Node  AIX      TESTNODE

So I checked the client process:

ps -ef  |grep dsm

Founding :

the backup process is existed:

So after I killed the process, the session is not existed:

then I updated the node:

tsm: TSM>update node TESTNODE maxnummp=2
ANR2063I Node TESTNODE updated.

--------------------------

Then I do the backup test manuualy:

sucess:

-----------------------

Then I test the schedule:

tsm: TSM>update sch sms_domain TESTNODE_daily starttime=now
ANR2502I Schedule TESTNODE_DAILY updated in policy domain SMS_DOMAIN.

Then kill the schedule process : dsmc sche &
Then restart the schedule process.

I will monitor the dsmsched.log

succuess result .
