computaboi Posted March 21, 2013 Report Share Posted March 21, 2013 [quote name='pawankalyan' timestamp='1362870935' post='1303395177'] I am attending some netapp classes.These are the some of the points i found important in that tutorial. May be helpful for very beginners. Summary: Aggregate is the combination of raid groups with the same raid type. raid group as limitation. each raid group as maximum of 16 drives in raid type Raid 6. each raid group as maximum of 8 drives in raid type Raid 4. * Aggregate as no limit for number of drives * There is no limit for number of raid groups in Aggregate. *There is a limit for aggregate size. But how we are getting the size limit. In 7.3 version of ONTAp. we have 32 bit aggregates In 8.0 version of ONTAP. we have both 32 and 64 bit aggregates. But default is 32 bit. The root agrregate is 32 bit. In 8.1 version of ONTAP. We have 64 bit aggregate as default size.we can also have 32 bit. * Lets Try to understand what is this 32 bit and 64 bit. block size on Netapp = 4k bytes disk block size is 512 bytes. * In 32 bit we can have 2^32 adrreses and we can store 2*32*4k=16 TB *In 64 bit we can have 2^64 addreses and we can store 2*64*4k=67 million PB. * 8.0 version FAS2040 ----30TB (Max Size) FAS6280 ----100TB(MAX SIZE) *8,1 Version FAS2040----50TB FAS6280----162TB We can create a raid group with less than the default raid size. the best practice is to have the raid groups with equal sizes in a aggregate to avoid performance issue. We can expand aggregate by adding additional drives.but we cannot remove drive from the aggregate Adding a drive doesn't have any performance issues. For data integrity we have blocked checksum & zoned checksum(Netapp using Blocked Checksum) Scrubbing is the thing used to check the error(bad blocks) in the disks. If we get more scrub errors it have a high propability of failure.we can find the scrub errors at /etc/messages. In a raid group netapp supports the disks with different sizes. But the highest capacity drive should be a parity disk. Netapp support FC and SAS drives existing within the same raid group since they have equal performance. we cannot intermix sata and saas or fc or sata. * Two types of volumes exists: ---->Traditional volume. ---->Flex volume. Flex volume: * Will be create within the aggregate. *Lowest volume size = 20MB. *Highest Volume size = 30TB for FAS2040. *There is a limit for number of volumes in filer.Varies from model to model. *Single filer has limit in number of aggregates. Maximum 100 agrregates per filer. *Agrregate should not have two volumes with same name. * We can increse or decrease the size of volume. Traditional volume: *We cannot decrease the size of the volume.but we can increase the volume *Maximum of 100 volumes can be created in an aggregate. Questions: * Why we are creating aggregate? Commands: *Creatingthe raid group: aggr create aggr1 *How many raid groups in aggregate: sysconfig -r (or) vol status - *How to know the spare drives in aggregate: aggr status -s *How to Get the broken or failed drives: aggr status -f *To Free the spare disk spaces: disk zero spares *Manually forcing the disk to fail: disk fail 0a.20 :so it will copy the data to new spare disk. *To make our job easy while removing the right drive from disk shelf is Run the following commands priv set advanced led off 0a.19 led off 0a.21 * To go back to admin mode: priv set admin so now we can identify our failing disk easily to remove. *To replace a disk manually with another disk: disk replace 0a.19 0a.21 * To delete all the data in the disk if we are selling this disks: disk sanitize 0a.19 : We should have license to run this command. * To read the scrub errors: rdfile /etc/messages. * To read the log files: rdfile /etc/log/auditlog * Creating volume : vol create vol1 aggr1 100m * Changing sizes : vol size vol1 +50m ----150m * To increase the volume size automatically: vol autosize -i 100m -m 500m on (This will increase 100m each time and increses upto 500m) * To create a traditiona volume : vol create tradvol1 24 * To add disks to traditional volume: vol add tradvol1 12 [/quote] Hey Pavan dude, Nenu kuda NetApp mida working, when I learned storage technologies I got good help from people in this forum 30yrs inka chala mandi. feel free to ask any questions that you may have with it, I will try and help asmuch as I can, all the best Quote Link to comment Share on other sites More sharing options...
