vxprint output description
- 9 years ago
Hello,
I would recommend to read through the guides to understand different types of volume layouts . Start with sf admin guide
To answer your questions
a) In this vxprint o/p, what does these 4 plexes means.. which type of RAID configuration it is, if there are 2 plexes or 5 plexes what would be the RAID configuration.
--> This depends on how volume was created. You can have two plexes in RAID 1 i.e. mirrored state (if both the size of plex is same), you can have them in concat or stripe. OR you can also have them in RAID 1+0 or vice versa which means concat-mirror, mirror-concat, stripe-mirror or mirror-stripe. These are called layered volumes. A layered volume will have an object called sub-volume which is denoted by "sv". You seem to have a sub-volume which indicates you might have a layered volume which may be concat-mirror or mirror-concat. Read through below link in detail

b) What is meant by DISKOFFS & LENGTH mentioned here.. in SD section. Does that size in 512-byte blocks or 1024-byte blocks?
Length would actually denote the size of subdisk in a volume .. depending on layout of volume, various sub-disks will form a volume. )Length x 512) / 1024 / 1024 /1024 will give you size in GB. you can try converting a volume size into GB. Diskoffs as the name indicates are disk offsets
c) What is 0 denoted here after LENGTH in SD section?
refer to legends at the beginning of the vxprint output, the sd line legends are
SD NAME PLEX DISK DISKOFFS LENGTH [COL/]OFF DEVICE MODE
the 0 here would indicate the column/offset
