Editing 2007 mercury upgrade

This was actually done as [[2008-10 mercury upgrade]] 2007-06: Immediate problem: we are running out of disk space on mercury ===Option A: External Disk Enclosure=== Need: * SCSI Cable * SCSI Disk Enclosure * Two SCSI Disks ===Option B: Upgrade One Disk=== Replace one of the internal 18s with a 36 or more. Advantages: most disk for the $ Disadvantages: no mirroring (however we don't have it now anyway.) ===Option C: Upgrade Both Disks=== Replace both internal 18s with 72s and mirror them. Advantages: * will upgrade available data space from 18G to about 54G which will last for a long time * very safe upgrade path: ** replace data disk with empty 72G ** copy boot disk over to new 72 and make it bootable ** boot from 72, patch and upgrade ** copy mercury zone over to new 72 ** pull out the data 18, install the second 72, and mirror onto it Then Dan can use the spare 18s in the backup disk tower at home. ===Option D: Rent Space From Moose=== Will require monthly $$ ===Disk Suppliers=== * http://discountechnology.com/discount-hard-drives-disk-arrays?partner=1000 * http://www.directdial.com/ca/shop/go/HARDDRIVES-SCSI.asp?menu=62,70, * Moose has MAW3147NP - 147GB 10K RPM, 68Pin, Ultra 320 $275 ==Method (Plan A)== # shutdown mercury. # copy mercury to an NFS mount -- cpio would be fine # insert new disk # boot from CD # cpio venus to new drive # boot from new drive # install other drive and mirror? ==Method (2007-06 version)== * Disk Installation ** Power on enclosure ** connect to venus console ** init 0 ** boot -r (or reboot -- -r from multiuser) * PCA Patch Update ** Best Practices PCABestPractices ** Download patches ** Install Patches ** Reboot * Update CSW packages ** setup auto-yes ** pkg-get -U * Container rebuild of Mercury ** Prereq: install disks. ** Prereq: run PCA to update patches etc. ** Prereq: update CSW patches.
