Re: [pca] Install patches on secondary submirror

[Bleek Thomas]

Hello,

you really should take the lu way. it is working great.





before switching to lu 2 years ago I did the following:

1. split the mirror
2. fsck the new root
3. mount it and edit vfstab
4. deleteing the last lines in /mnt/etc/system
5. deleting *.cf in /mnt/etc/lvm/
6. patching





Once more:

Take LU!

If you need assistance with lu, write directly,
thomas

if this is an important system you should test the procedure (lu or splitting mirror) on another system. if you do the split, you should think of /etc/system (look at the last lines) and also of the *.cf files in /etc/lvm/. the main disadvantage is, that you have to create the mirror again (additional reboot). I'm sure, that there is a more elegant way to do this, but it has worked for me.

Hi All


Has anyone done it with detail/complete steps?

Here is how my SVM looks like

(root)@myhost:~# metastat -p
d0 -m d20 d10 1
d20 1 1 c1t1d0s0
d10 1 1 c1t0d0s0
d1 -m d11 d21 1
d11 1 1 c1t0d0s1
d21 1 1 c1t1d0s1

(root)@myhost:~# metadb
        flags           first blk       block count






my /var, /opt and /usr are part of root /

(root)@myhost:~# df -h /var
Filesystem             size   used  avail capacity  Mounted on
/dev/md/dsk/d0         9.8G   5.5G   4.2G    57%    /
(root)@newsunray:~# df -h /opt
Filesystem             size   used  avail capacity  Mounted on
/dev/md/dsk/d0         9.8G   5.5G   4.2G    57%    /
(root)@newsunray:~# df -h /usr
Filesystem             size   used  avail capacity  Mounted on
/dev/md/dsk/d0         9.8G   5.5G   4.2G    57%    /

Q: Why is top-posting such a bad thing?

I want to install patches on secondary submirror on this box. I could use lu to setup an ABE and then mount that and install patch on that. However, if I don't want to worry about installing lu and recommended lyu patches, I could just detach the secondary submirror and mount that and install patch on that as well. Then modify the vfstab on the secondary submirror and just boot from that. a m p luo 16 8192 /dev/dsk/ c1t0d0s6 a p luo 8208 8192 /dev/dsk/ c1t0d0s6 a p luo 16400 8192 /dev/dsk/ c1t0d0s6 a p luo 16 8192 /dev/dsk/ c1t1d0s6 a p luo 8208 8192 /dev/dsk/ c1t1d0s6 a p luo 16400 8192 /dev/dsk/ c1t1d0s6 So I can just detach the d20, and remove the metadb c1t1d0s6, and mount it and change the vfstab and systems file. use eeprom to make c1t1d0s0 as the correct boot-device root. Then install patch on that using pca and boot from it. That should work, correct? Lets say I mount d20 on /mnt. So can I patch that like this? pca - a -i mrs -R /mnt ?
