Post subject: | Migrating system LDs from FC to SSD (AFA) |
Hi, I have a 7440c running v3.2.2 which i'm trying to migrate from FC to SSD entirely. It had 20x 600GB 10K disks, and i have been dismissing the first 12x PDs and relocating chunklets without issues, the next 6 disks could be forced with light complaining. So i have 2 remaining disks, and i can not get them evacuated over to the SSDs. I added the SSDs as i free'd physical slots, but the system volumes (srdata & admin) will not move over to the SSDs. I used the following command for the first 12 disks: movepdtospare -f -vacate -nowait <PDID> And this for the next 6: movepdtospare -devtype -ovrd -perm -nowait <PDID> But for the last 2 PDs, the above command fails with: Error: Could not find relocation target for one or more chunklets Following other guides from this site and elsewhere, i have deleted "pdsld" and "log" and tried disabling system reporter to be able to delete the srdata volume, pdsld and log is deleted successfully, but i can not delete srdata and admin, both gives the error "Ld <LD> is in use" Finally i tried just powering down the system with the 2 remaining disks, removed them and added the 24x blank SSDs, but on power up the system then complains about "Table of contents (TOC) quorum not reached." and the system is unusable, i tried running setsysmgr tocgen, but that didn't help either. Do you have any suggestions on how to migrate to all-flash "the right way" without having to do a OOTB? The system is empty, so i *could* do a OOTB and be done with it, but i want to treat it as if i had data on it. This is for a "homelab" and as such i have no contract with HPE. Thanks for your time! |

Grats, nice home lab! I don't know the answer, but curious of the admin and srdata are physically provisioned, or if they are assigned to a CPG. If CPG, then can you set the CPG to DEVTYPE = SSD (it;s probably FC now) showcpg –sdg This thread may also have some useful tidbits: viewtopic.php?f=18&t=3117 |

Hi! Thanks for your reply. I think they are physical, they don't have any CPG associated, do you have any idea how i can run them on a CPG instead of physically?
