1. How to improve the Netapp storage performance?
There is no direct answer to this question but we shall do it in several ways. 1. If volume/lun present in ATA/SATA hard disk aggregate, then the volume can be migrated to FC/SAS disk aggregate. Either you can use flash cache to improve performance. 2. For NFS/CIFS instead of accessing from a single interface, multi-mode vif can be configured to get better bandwidth and fault tolerance. 3. Always advised keeping aggr/vol utilization below 90%. 4. Avoid doing multiple volume backups at a singl...
2. Unable to map lun to Solaris server, but Solaris server-side no issue. How to resolve the issue?
FROM THE STORAGE SIDE: 1. Verify iscsi/fcp license is added to the storage 2. Verify iscsi/fcp session is logged in from server-side use below command 3. Netapp> igroup show -v 4. Verify luns are mapped to the corresponding igroup 5. Verify whether the correct host type is mentioned while creating igroup and lun 6. Verify whether the correct iqn/wwpn number is added to igroup 7. Verify zoning is properly configured from the switch side if it is FCP protocol
3. How to create the LUN for the Linux server?
lun create –s size –t Linux /vol/vol1/lunname
33. What do you do if a customer reports a particular CIFS share is responding slow?
1. Check the r/w using “cifs stat” & “sysstat -x 1”. 2. If disk & cpu utilization is more then the problem is with the filer side only. 3. CPU utilization will be high if more disk r/w time, i.e., during tape backup & also during scrub activities.

48. Explain the different types of replication modes?
1. SnapMirror semi-sync: It offers a middle ground solution that keeps the destination and source systems more synchronized than the Async mode, but it will focus less on performance. 2. SnapMirror Sync mode: At the same time, It performs a write function from a source volume to a destination volume. This mode is used in a case, where there is zero-tolerance for data loss. 3. SnapMirror Async mode: It transfers snapshot copies from either qtree or source volume to a destination. Using the sna...
