How to increase Thin Volume when they are 100% Allocated
Hello,
I'm receiving the following alerts from pour VMAX:
Description: Thin Device is now 100 percent used. - Object is: xxxxxxxxxxxx:1969
Severity: FATAL
State: NEW
Managed Object: 14AD
Pool Pool Total Compressed
Sym FLG Total Sub Allocated Written Size/Ratio
Dev T MBs (%) MBs (%) MBs (%) MBs (%)
----------------------------------------------------------------------
14AD B 131074 0 110595 84% 131071 100% 110595
I don't know if I need to increase volume size or if I need to set a policy in that volume in order to clean those alarms. As you can see the TOTAL WRITTEN IS AT 100%

You will need to have a chat to the owner of the volume to work out your course of action. Just because the volume is 100% written, does not mean the file system is full, or if it is a database, that the tables are full.
If the volume volume manager is thin friendly, you may be able to reclaim some (zeroed) space on the volume also. Through symconfigure command line, the syntax is "start reclaim on tdev "

You right, actually I checked the file system is not full. I logged into the Windows server and I can see that the drive has some free space.
On the other hand, I'm receiving alerts regarding the THIN Pool is 100% written.. I just want to re-size the volumes if I need or run a reclaim or do something to clean the alerts. I don't want to desable the alerts. What commands should I run there?
Thanks.

The reclaim command syntax you can refer:
symconfigure -cmd "start free on tdev xxx start_cyl=0 end_cyl=last_cyl type=reclaim;" -sid xxx -nop commit
Before you run the command, you'd better to go through the following doc for considering file system & array side:

Thanks Fenglin Li.,
What I dont understand is why I'm supposed to do a reclaim instead of re-size de volume. or why it shows 84% for Pool Allocated and 100% of total written.
Thanks a lot to all of you guys for replaying to this post.
