Reclamation

[bprrajeev]

Hi



Can anybody help me how I can set reclamation in my storagepool.

My storage pool structure is like this, in my sequential access storage pool I have LTOPOOL1, in that I have 14 media labelled as ADSM01, ADSM02,...

everytime I have to manually scratch the next volume for the backup.

How I can set reclamation successfully, so that I do not make the volume scratch manually.



Thanks in advance

Regards

Rajeev

it s all depende to have much the tapes are used!





i think u should do a admin script wich lunch the reclaim every day

for example if you re backup take place in the night (from 20h00 to 07h00)



lunch the reclaim every day from 09h00 to 18h00 !

Thanks in advance

so



I have an Admin Script ( Object view =>Automation => Administrative command schedules ) wich is scheduled every day at 02h00 PM :



upd stg LTOPOOL1 reclaim=60 ==> wich start the reclamation for that TSP pool



and an another Adminscript scheduled every day at 06h00 PM:



upd stg LTOPOOL1 reclaim=90 ==> Stop the reclamation after the running process finished.





is this clearer?

What is the delay reuse setting for the storage pool? Make sure its set to 0 so a reclaimed tape immediately goes to scratch. Also the process listed in the other posts will automate it.

What Chad says is good for onsite pools. For offsite pools I define the reuse delay to be equal to the number of days that we keep database backups.

can you run this command :



select VOLUME_NAME,STGPOOL_NAME,PCT_RECLAIM from volumes where PCT_RECLAIM > 60 order by PCT_RECLAIM

 

[bprrajeev]

Hi,



Thankyou,

When I run the command it shows the following,



VOLUME_NAME STGPOOL_NAME PCT_RECLAIM

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

ADSM10 LTOPOOL1 90.9

ADSM03 LTOPOOL1 98.1

ADSM07 LTOPOOL1 99.0

ADSM08 LTOPOOL1 99.5

ADSM09 LTOPOOL1 99.5



Please see it,



Thanks

so,



you have 5 tapes wich can be reclaimed in the LTOPOOL1.



but if I am right it's not the STGpool u wanted to reclaim ==> RECLAIMPOOL



that's it??



dis youy run Expire Inventary every day? and is it going till end ?



if it is, sorry but you no choice but increase your "Maximum Scratch Volumes Allowed" and allow more tape to this STGPOOL.

because there is no place on the STGpool.



Can you give us the definition of your "RECLAIMPOOL" stg pool??

 

[bprrajeev]

Hi,



LTOPOOL1 is the stgpool which I wanted to reclaim, there are 14 medias labelled.

And the maximum scratch volume allowed is 100, ithink it is enough.



You can see the following storage pool structure.



Sequential Access Storage Pools



Storage Pool Name Description

LTOPOOL1

LTOPOOL2

RECLAIMPOOL



Thanks

i am missing some thing,



euuuuuuuuhh...



are you reclaiming your LTOPOOL1 on RECLAIMPOOL ??



if so,



today you get 5 volumes wich need reclaimation on the LTOPOOL1,



but if you don' t have scratch volumes on RECLAIMPOOL (and so there is because the command u passes demonstrated that there is no volumes needind reclaimation on it)



the reclamation will failed.



why dont reclaiming LTOPOOL1 on it s own ?

why not labeling more tapes for LTOPOOL1 ?

 

[bprrajeev]

Hi,



I wanted to reclaim LTOPOOL1 to its own,

how can I change it, ok First I can delete the RECLAIM POOL.

then what step i need to take?



Pls help

Thanks

Rajeev

 

[may]

No



don t delete RECLAIM POOL , because all your primary data wich were reclaim on LTOPOOL1 are on it, so don t delete it!



to change the configuration of the LTOPOOL1 to do the reclamation on it own by the gui



Object view ==> Server Storage ==> Sequential Access Storage Pools ==> LTOPOOL1 ==> "Update Sequential Access Storage Pool" ==> Reclaim to storage pool ==> choose the "" option.



Now

to retriew all the volumes from RECLAIM POOL to LTOPOOL1

you have to update the RECLAIM POOL

and set LTOPOOL1 as "Next Storage Pool" on it.

do an "upd stg RECLAIMPOOL hi=0 lo=0"



be aware that you should have some scratch volumes available

 

[bprrajeev]

Hi,



I have checked it, In the LTOPOOL1 configuration, reclaim to storage pool options only two POOLS are available, LTOPOOL1 is not available there. The other two pools are LTOPOOL2 and RECLAIMPOOL.



And in the RECLAIMPOOL configuration the next storage pool is already set as LTOPOOL1.



Thanks

Rajeev

 

[may]

u should have a "" option avalaible too



("") mean "nothing"

 

[bprrajeev]

Hi,



YES it is right and I updated with the same,

But you can see the configuration of LTOPOOL1 shows that no reclamation is runing.



Reclamation Threshold 60

Maximum Scratch Volumes Allowed 500

Delay Period for Volume Reuse 0

Migration in Progress? No

Amount Migrated (MB) 0.0

Elapsed Migration Time (seconds) 0

Reclamation in Progress? No





Pls see



Thanks

Rajeev

 

[may]

u can do a

"upd stg LTOPOOL1 reclaim=40"

and inthe run

"upd stg LTOPOOL1 reclaim=60"



it should lunch a reclamation for a least one volume.







or u can use this command (i haved already given to you) to if there some volumes who nedd reclamation



select VOLUME_NAME,STGPOOL_NAME,PCT_RECLAIM from volumes where PCT_RECLAIM > 60 order by PCT_RECLAIM

 

[bprrajeev]

Hello



I have run the command

and it shows i think the same like last time



VOLUME_NAME STGPOOL_NAME PCT_RECLAIM

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

ADSM10 LTOPOOL1 97.7

ADSM03 LTOPOOL1 98.1

ADSM07 LTOPOOL1 99.0

ADSM08 LTOPOOL1 99.5

ADSM09 LTOPOOL1 99.5
