Huawei H13-629 Exam - Topic 1 Question 14 Discussion

Actual exam question for Huawei's H13-629 exam

Question #: 14
Topic #: 1

Existing set customer of database uses a raw device, due to the large amount of data in the database. The customer plans to replace the old storage with new storage devices.

In the process of environmental inspection lvcb engineers found the following:

#getlvcb -TA sjklv

Intrapolicy =

copies = 0

interpolicy =

lvid =

lvname =

label =

machine id =

number Ips = 0

relocatable =

strict =

stripe width = 0

stripe size in exponent = 0

type =

upperbound = 0

fs =

time created = time modified =

As the vg is too large, the expansion of vg is impossible. As the service window is very short, and customers do not want to avoid the risk of large adjustments of the whole original environment, what is the recommended approach?

ABased on lvcb offset reconstruction nude equipment, and the database level 0 backup import

BUse the dd command for data migration

CUse the cplv command for data migration

DUse migratepv for data migration

Show Suggested Answer

Suggested Answer: A, C, D

I’ve always used dd for this kind of stuff. Works like a charm!

Option B is faster, but risky. Not sure it's worth it.

Wait, can we really use migratepv with such a large vg?

Definitely agree with that! Migratepv seems reliable.

I think option D is the safest choice for data migration.

Based on what I studied, I think option A might be risky since it involves reconstructing offsets, which could complicate things if the environment is already unstable.

I have a vague recollection that cplv is more for managing logical volumes rather than actual data migration. Not sure if it's the right fit here.

I'm not entirely sure, but I think using dd could lead to data loss if not done carefully. I feel like we practiced a similar scenario in class.

I remember we discussed the importance of minimizing downtime during migrations, so maybe option D with migratepv could be the safest choice?

Hmm, gap analysis... I'm not totally sure what that is or why it would be done. I'll have to think this through carefully.

Definitely option D for me. The whole point of these tools is to empower the front-line Service Desk staff to handle simple problems on their own, freeing up the more experienced teams to tackle the tougher challenges.

Wow, this customer really likes to keep things interesting, don't they? I'd go with option D - migratepv seems like the most straightforward and reliable option here. Though I can't help but feel that the engineers need to do a bit more 'getting lvcb' and a bit less 'getting coffee.'

Hmm, this is a tricky situation. Since the VG is too large for expansion, I'd be hesitant to go with option B or C as they may not handle the data migration reliably. Option D using migratepv seems like the safest bet to me.

The lvcb information provided suggests there may be some underlying issues with the current storage setup. Using a raw device and the lack of copies and stripe width seems concerning. I think option A might be the best approach to safely migrate the data with a level 0 backup.
