Hello,
Please share the command to get flash doms on aix
Best regards,
Vishal
Please explain what problem you are having. I'm assuming that you have searched on the IBM site, but I find nothing relevant. Please confirm what you are looking for or explain the function that is not working.
Do you mean flash prom perhaps, or is it domains? I regret that I'm rather confused. 
Robin
The volumes have been migrated to flash(solid state disk) and how do I detrmine at os level that which all file systems have been moved to SSD
I tried with lslv and lspv but could not get much info.Please assist.
Best regards,
Vishal
I understand the "flash" bit, just not the "doms"
The output you are probably looking for will be from lscfg Assuming that you have a volume group of two devices (to make it easy) of which one is real spinning disk and one is SSD, you could get output like this:-
$ lscfg -vl hdisk1 |grep hdisk
hdisk1 U789C.001.DQD5S24-P2-D4 SAS Disk Drive (300000 MB)
$ lscfg -vl hdisk2 |grep hdisk
hdisk2 U789C.001.DQD5S24-P7-D2 SDD Flash (300000 MB)
Of course you will probably have different disk types, perhaps a RAID device or a SAN LUN assigned.
You will need to check which filesystems are on spinning disk (hdisk1 in my example):-
$ lspv -M hdisk1
This might produce quite a lot of output, so probably best to catch it to a file. You can then move the logical volumes with migratepv Depending on mirrored LVs and available space on each target disk, you may be better moving each logical volume under your control:-
$ migratepv -l lv_01 hdisk1 hdisk2
If you are sure that the target disk has sufficient space to do it all in one go, you can just
$ migratepv hdisk1 hdisk2
The process will probably take a while. Each allocated PP is copied and synced in turn before the old one is removed, whether there is data in it or not, so a 500 Gb filesystem with 200 Mb used will take ages to move, however this can all be done with the filesystem active.
You will have to ensure that if your LV is mirrored, that you do not violate the rules keeping the various partitions separate.
I hope that this helps. For completeness of the thread, it would be good if you can post the output of the disk types.
Kind regards,
Robin
Hello,
Below is the output:
lscfg -vl hdisk4|grep hdisk
hdisk4 U8233.E8B.1097BDP-V6-C108-T1-L8500000000000000 Virtual SCSI Disk Drive
Does this mean that this is not on SSD?
Also this hdisk4 comes through SAN Volume controller so how to check for SSD?
Best regards,
Vishal
hmm... somehow the things you state do not add up to a coherent picture.
You can use the "lsattr -El <device>" command to get more information about a device - such as a disk. If your concern is that the SSD disks are visible at all to the system, then this is the way to go. Notice, though, that you will only see directly connected disks this way. What you have shown is a "virtual SCSI" device. I suppose your LPAR got it from a VIOS. You will not be able to see the properties of the physical disk from the LPAR in this case, because it gets the disk without caring where it comes from (just like a file doesn't care what the filesystem it resides at is made from). You will have to log on to the VIOS (or whatever exports the disk - SAN fabric, ...) and look there.
If you have made sure there is a SSD device your system recognizes as a "hdisk" device you may wonder if it is part of a certain volume group. Issue "lspv" in this case and see all the physical volumes along with the volume groups they belong to.
If you are sure a PV is part of a certain VG and wonder if a certain logical volume is on this PV issue a "lslv -m" to get a map file f the LV.
I am still not sure what you are about (you might consider taking a step back, drink a coffee to come down, then explain what your problem is v-e-r-y s-l-o-w-l-y and concisely), but anyway, i hope this helps.

Ah! you are using vscsi so you won't really be able to make it out from client which disk is SSD.
Best bet is your VIOS, you can run lsdev -Ccdisk paste the output here.
Below is the output from the server:
lsdev -Ccdisk
hdisk0 Available Virtual SCSI Disk Drive
hdisk1 Available Virtual SCSI Disk Drive
hdisk2 Available Virtual SCSI Disk Drive
hdisk3 Available Virtual SCSI Disk Drive
hdisk4 Available Virtual SCSI Disk Drive
hdisk5 Available Virtual SCSI Disk Drive
hdisk6 Available Virtual SCSI Disk Drive
hdisk7 Available Virtual SCSI Disk Drive
hdisk8 Available Virtual SCSI Disk Drive
Do you want me to login to VIOS and check the same thing for these lpar?
Best regards,
Vishal

I see no SSD here. Are they all hidden in the SAN? If that is the case, then you have to go to the SAN and see what comprises the LUNs it offers to the VIO server.
You may need to use lsmap on the VIO servers to connect each LV (as the VIO sees them) to the hdisks on the user LPAR.
Robin
2145 are SVC's (an inline virtualization), have you asked the storage admin whether they have SSD's (storage array) connected to same SAN as this one? I hope they are NOT playing mix and match on SAS's and SSD's.
I don't know why but I still believe they are all SAS disks.

Sorry this is partial/noob answer and nothing harm. But i will check like this.,,
datapath query essmap | grep hdisk4
You will get Which RAID it is from.
Then ask your Storage Person whether this RAIDX is SSD or not.
@Thala
1st thing 1st, do you think ESS has any disk model type 2145? (or for matter 2076)
Also, do you think any command for ESS storage work on SVC?
If I consider, this to be true (which I don't), do you think SVC will give you RAID type? Is it not a logical LUN, carved out of one or more mdisk.
Can you explain me this please.
Oh sorry I didnt notice 2145 !!!
