The current box has 2 logical drives, shown in P410i Array Controller (F8 during POST) as:
- Logical Drive 1 - 2 SAS 72GB HD Raid10 <----root pool disk
- Logical Drive 2 - 4 SAS 146GB HD Raid 5 <----data disk
And this is what it shows in the OS :
bash-3.2# echo | format Searching for disks...done AVAILABLE DISK SELECTIONS: 0. c0t0d0 <HP -LOGICAL VOLUME -5.06 cyl 17841 alt 2 hd 255 sec 63> /pci@0,0/pci8086,3408@1/pci103c,3245@0/sd@0,0 1. c0t1d0 <HP-LOGICAL VOLUME-5.70-410.10GB> /pci@0,0/pci8086,3408@1/pci103c,3245@0/sd@1,0 bash-3.2# zpool status pool: rpool state: ONLINE scan: none requested config: NAME STATE READ WRITE CKSUM rpool ONLINE 0 0 0 c0t0d0s0 ONLINE 0 0 0 errors: No known data errors pool: rpool-app state: ONLINE scan: none requested config: NAME STATE READ WRITE CKSUM rpool-app ONLINE 0 0 0 c0t1d0 ONLINE 0 0 0
The size of current rpool (c0t0d0) is too small which is 72GB. I want to increase the rpool by putting in new hard disks (2 SAS 146GB). After I create the new logical drive for these 2 drives, it appears in the Controller as Logical Volume 3 and in the OS as c0t2d0. In the OS, i format c0t2d0, attach it to the rpool to have it mirrored then i detach the c0t0d0. I make sure the new disk is bootable by setting
eeprom bootpath= new device
When i reboot the server and access the controller (F8), i also go to Select Boot Volume and select Logical Volume 3 as the new current boot lun. The server is able to boot up and picking up the new boot device correctly. However, I don't see 2 previous disks there anymore (c0t0d0 and c0t1d0).
bash-3.2# echo | format Searching for disks...done AVAILABLE DISK SELECTIONS: 0. c0t2d0 <HP -LOGICAL VOLUME -5.06 cyl 17841 alt 2 hd 255 sec 63> /pci@0,0/pci8086,3408@1/pci103c,3245@0/sd@2,0
I tried everything, devfsadm or cfgadm and reboot many times to check the status of those Logical Drives in the Controller, they are still there with OK status. But i don't know why i no longer see them in the OS. c0t0d0 is the old boot disk that i don't need anymore, but c0t1d0 is the data disk and i need it to show up here. Do you have any clues?
