How to Replace a SPARCstorage Array Tray

When you have completed work on a SPARCstorage Array tray, replace the tray in the chassis. The disks will automatically spin up.

However if the disks fail to spin up, you can use DiskSuite Tool (or the ssaadm command) to manually spin up the entire tray. There is a short delay (several seconds) between starting drives in the SPARCstorage Array.

After the disks have spun up, you must place online all the submirrors that were taken offline. When you bring a submirror online, an optimized resync operation automatically brings the submirrors up-to-date. The optimized resync copies only the regions of the disk that were modified while the submirror was offline. This is typically a very small fraction of the submirror capacity. You must also replace all state database replicas and add back hot spares.

If you used metadetach(1M) to detach the submirror rather than metaoffline, the entire submirror must be resynced. This typically takes about 10 minutes per Gbyte of data.
