On a NetApp FAS9000 system, which two field replaceable units (FRUs) are supported for replacement without takeover? (Choose two.)
FRUs on FAS9000 Supporting Replacement Without Takeover:
A (I/O Module): I/O modules can be replaced hot (without takeover) to maintain system uptime during hardware servicing.
D (NVRAM Module): NVRAM modules on FAS9000 can also be replaced without a node takeover, ensuring data integrity during replacement.
Why Other Options Are Incorrect:
B (DCPM Module): The DCPM (Data Center Power Management) module is not hot-swappable and requires a node takeover.
C (Caching Module): The caching module is integrated and typically requires a node takeover or power-down for replacement.
NetApp Reference Documentation:
Refer to the 'NetApp FAS9000 Hardware Service Guide' for supported FRU replacement procedures and operational constraints.
At what stage is a write acknowledged to a client?
Write Acknowledgment in NetApp ONTAP:
In a clustered ONTAP system, write requests are acknowledged to the client only after they are securely stored in NVRAM on both the local node and its HA (High Availability) partner.
This ensures redundancy and data protection in case of a node failure.
Why Other Options Are Incorrect:
A . when the write is present in the local node RAM and NVRAM:
Writes are not acknowledged until the HA partner also stores the data in its NVRAM.
B . when the write has been flushed to disk:
Writes are acknowledged before they are written to disk, as NVRAM ensures durability.
D . when the write has been flushed from NVRAM to RAM:
Data is not acknowledged based on RAM; NVRAM on both nodes is the requirement.
NetApp's 'ONTAP Write I/O Processing Guide' explains the role of NVRAM and HA in write acknowledgment.
'Data Protection in ONTAP' highlights the synchronization of NVRAM between HA partners.
Which two tools can be used to recover an inconsistent aggregate? (Choose two.)
To recover an inconsistent aggregate, the following tools can be used:
1. wafl_check
What it does: This tool is used to perform a consistency check on WAFL metadata. It identifies and attempts to fix WAFL inconsistencies in aggregates.
When to use: Run wafl_check after identifying WAFL inconsistencies to repair minor metadata issues.
2. wafliron
What it does: This tool repairs WAFL inconsistencies by reconstructing metadata. It is more powerful than wafl_check and should only be run under NetApp Support guidance, as improper use can result in data loss.
When to use: Use wafliron for severe WAFL inconsistencies that cannot be resolved by wafl_check.
Why Other Options Are Incorrect:
A . file check:
This is not a valid NetApp tool.
C . wafl snapiron:
While similar in name, snapiron is used for snapshot recovery, not aggregate recovery.
'ONTAP Aggregate Troubleshooting Guide' details the usage of wafl_check and wafliron.
NetApp Support documentation provides guidelines for recovering inconsistent aggregates.
